Zac Efron might be blessed with a killer smile and heart-stopping physique, but that head of perfectly tousled hair, could it possibly be effortless too? “I’ve never told anyone this before. This is a hair scoop,” the Me and Orson Welles star tells Time as part of their “10 Questions” series before revealing his DIY steps. “Shower before you go to bed, and then sleep on your wet hair. Towel-dry it. In the morning, it’s all messed up naturally. If you have that messed-up thing going when you wake up, it’s more willing to stay that way. That’s Zac’s hair tip.” Learn more of Zac’s secrets as he answers readers’ burning questions at time.com.

We’re all for a little style experimentation, but when we spotted beauty mavens Ashley and Mary-Kate Olsen at MoMA’s Film Benefit honoring Tim Burton this week in New York we were more than a little perplexed. We’d gotten used to Mary-Kate being the style risk-taker and her twin Ashley taking a more conservative approach. But the duo played with our expectations, with Ashley adding rainbow stripes to her hair and her sister going as bold as ever with the deepest red lips around. Tell us: What do you think of the sisters changing it up? What’s the boldest look you’ve tried in the name of beauty?

If you’re one of the lucky few to have been crowned Miss USA, chances are that you know a thing or two about beauty. And Shanna Moakler is making the most of her makeup know-how with a new line of organic pressed mineral makeup co-created with her personal makeup artist, Daniel McFadden. While the Smoak collection launched just this week, Shanna tells PEOPLE that her love of makeup started at a young age. “My mom is beautiful and had that ’70s kind of glamour,” she says. “My love of lip gloss comes from my mom, who always wore it — and from watching Charlie’s Angels.” Smoak does feature a rainbow of glosses, but it also encompasses everything from eyeliners and eye shadows to blushes and foundation, all based on the Miss California USA host’s principle that makeup should be as fun as it as functional. When women come to her for beauty advice, Shanna tells them to take a carefree approach and experiment. “Don’t be afraid to try new colors,” she says. “If you see a look in a magazine that you like, try it. You know your face better than anyone. Find the tricks that work for you. When you take a little time to put makeup on, it changes your confidence level and you radiate that. It can change your whole day.” Buy the line, which ranges from $8-$39, for yourself at SmoakShop.com.–K.C. Baker

“Yes,” it’s more fun to be blonde, Katharine McPhee told PEOPLE at a Calvin Klein Collection, Cinema Society and Sony Pictures Classics-hosted screening of Broken Embraces at the Crosby Street Hotel on Tuesday night. But is it more work to stay blonde? McPhee also answered with a decided, “Yes!” So how often does the singer have to visit her colorist to maintain her platinum locks? “Depending on what I have going on,” she said, “every three-and-a-half, four weeks. Right now I’m almost at the too dark roots stage. So I get to play around with hats.” The short coif is also relatively new. “Peter Savitt cuts my hair. This is the same haircut I had during Fashion Week, but it’s just been growing out and I’ve been flattening it.” But changing up her do has provided a surprising side effect — throwing off the paparazzi! McPhee revealed, “I’ve gone for a doctor’s appointment in Beverly Hills. And they say, ‘Oh, don’t go out that way. there are tons of paparazzi.’ And I say, ‘Don’t worry, they won’t recognize me.’ It’s been nice.” Vote on more star hair changes here!–Jeffrey Slonim

Call it method hair. When Sandra Bullock dyed her naturally brunette hair a golden blonde to play real life Memphis housewife Leigh Anne Tuohy in her film The Blind Side, her family had a distinctly unfavorable reaction. “They didn’t like it at all,” Bullock told PEOPLE at the New York City premiere of the film due in theaters Nov. 20. “It was entertaining for a couple of months but it’s not really my color palette.” In fact, Bullock says her husband, Monster Garage star Jesse James, did not find her lightened tresses attractive, which was a big relief. “Thank God an important person in my life didn’t want me being blonde. He was like, ‘I don’t like the blonde on you,’” she says. “You want him to say that!” Having experienced a lighter hairdo for months, does the old wives tale that blondes have more fun than brunettes hold true for Bullock? “Not at all” according to the natural dark brunette star. “Fun is what you make. Nobody is going to bring you the fun,” she said. “You got to go out and get it your fun.” One thing Bullock definitely did have fun with was playing a strong feisty woman with a quirky firecracker personality. “There’s no one else like her,” she says of Tuohy. “I’ve never met anyone else like her and I wish there more like her. She doesn’t care what people think. She and I come from very different viewpoints and we meet in the middle very easily because you realize the differences are not that great.” She adds, “I feel very humbled to have been a part of this. The whole experience to me was a once in a lifetime experience. I feel very lucky.” – Paul Chi

Her fans might envy Whitney Port for always looking perfectly put-together, but The City star is sharing the beauty wealth by appearing in her blog makeup-free — and revealing her favorite tips for dolling up. “I am not a big fan of heavy makeup,” she says, “so the majority of the time I do my own. I stick to the basics of face powder, bronzer and blush.” Her five-minute plan to getting gorgeous without a personal makeup artist? “I start by mixing Fresh High Noon tinted moisturizer with the Fresh Soy Face Cream to get a nice base with a little sunkissed glow. Then I dust Bare Minerals Powder with SPF 15 to even out my skin. Next I bronze with Guerlain Number One for Blondes on my cheeks, hairline and jawline. Then I brush a little bit of NARS Orgasm Blush on my cheekbones, a little on my forehead, nose, and chin to keep it constant. I use Anastasia brow gel to give my eyebrows a nice shape (this is especially helpful if I haven’t had time to go in to get them done.) I highlight under my eyebrows with Benefit Eye Bright and then curl my lashes with a Sephora eyelash curler. Sometimes if I’m really feeling like going all out for the day I put on Maybelline mascara.” Read more from Whitney on her blog. Tell us: Do you prefer Whitney with or without makeup?

Twilight’s Ashley Greene might have looked red-hot at last night’s L.A. premiere of the film series’ latest installment, New Moon, but she tells PEOPLE that finding her perfect scarlet Prabal Gurung stunner was no small matter. “We picked a dress out, had it ready,” Ashley says of a different look, which she originally chose with her stylist. But at the last minute, “I decided I didn’t like it and we had to start from scratch.” Just how down to the wire did it get? “I stopped by the tailors right before I got here to pick up the dress,” she admits. The rest of her red-carpet prep, however, was less of an ordeal. For two hours on the Sunday before the premiere, Ashley received eyelash extensions from expert Calma Yom at The Parlour on 3rd and then returned to the salon to have her hair extensions freshened up the following day. As for her bronzed skin, Ashley looked to St. Tropez tanning expert Fiona Locke, who customized and contoured her skin before the big event. The final touch came at the hands of makeup artist Vanessa Scali, who created the ’60s-inspired look for the Twilight star with “well-defined eyes with lots of lashes, a strong brow and clean skin with subtle pink [and] coral cheeks and lips.” Tell us: What did you think of Ashley’s head-to toe premiere style last night? –additional reporting by Lisa Ingrassia

Emma Roberts hit the The Prada Book launch on Friday in Beverly Hills with brand new sexy blonde hair color, and the Hotel for Dogs star talked to PEOPLE about whether she thinks the old cliché rings true. “I don’t think I need to be having any more fun these days!” she joked. But that doesn’t mean the actress won’t be testing out the theory. “I leave for New York in a few days and I think, what better than to show off my new hair than in New York to see if, you know, blondes do have more fun!” So why the sudden change? Emma explains that in addition to just wanting to “change it up,” the new look is also helping her to get into character for her newest film, It’s Kind Of A Funny Story. “I start shooting in New York next week and I wanted to do something different,” she explains. “I play a girl in mental institute that cut her face up with scissors. So I thought my face is going to be cut up I may as well have beautiful hair!” Tell us: What do like Emma better as a blonde or a brunette?–Kristin Larson

Kate Moss might have built a multi-million dollar career on her looks, but, she says, her appeal is more than skin deep. “It sounds really corny, but I think that if you’re beautiful inside, it shows on the outside for sure,” she tells WWD in an interview timed with the European launch of her fourth fragrance, Vintage. “You can be a pretty face, but if you’re not a nice person it just doesn’t work. I’m not traditionally a beauty, but apparently people think I’m all right.” And of course, there is always the personality factor. Kate elaborates, “If you’re a nice person, it definitely helps.” This doesn’t, however, mean that the original waif would let herself go. Her motto for keeping her figure in check? “Nothing tastes as good as skinny feels,” she says before adding, “You try and remember, but it never works.” Read the full interview at WWD.com.

While she may play tough as nails detective Olivia Benson on Law & Order: Special Victims Unit, this Hollywood actress is showing off her big heart, by using her spare time to give back to women in need.

Along with her handsome hubby Peter Hermann, celeb pals Debra Messing, Sharon Lawrence and Shohreh Aghdashloo and other volunteers, the group filled the kits with philosophy’s charity shower gel, a cozy shirt from Michael Stars and other goodies. “These kits say to a survivor: you’re not alone,” Hargitay told PEOPLE. “ I want to inspire these women with a sense of joy and possibility.” Hargitay partnered with philosophy to create a shower gel and body lotion which 100% of proceeds go to her Joyful Heart Foundation. “These products are so beautiful,” gushed a proud Hargitay. “The make women feel so good, it’s about watering your soul and heart and feeling good.” Support the cause by purchasing your own Joyful Heart shower gel, $20, from philosophy.com.– Jen Garcia

Kellie Pickler may be one of country’s most iconic blondes — she’s even impersonated Dolly Parton — but for now, she’s joining a less represented segment of the music community: redheads! The bombshell debuted her newly auburn locks on the red carpet of the CMA Awards tonight, having carefully tucked them under a hat for Parton’s Live from London DVD premiere party on Tuesday night. Pickler joked of the attention her new do is getting on the red carpet, saying, “It seems to be the thing to talk about.” She also gave a shout-out to legendary country redhead Reba McEntire, suggesting that she was joining her ranks since “we’ve got enough blondes in country.” But, she did admit to PEOPLE that she is still adjusting to her new do. “The hair doesn’t make the person, but it has been a shocker. I wake up in the morning and walk by the mirror and I’m like, ‘Who’s that!’ I thought someone broke into my house!” Pickler did manage to find the upside, explaining that, “It’s been interesting with red hair cause you can’t wear the same things. It’s an excuse to go shopping.” What do you think of Kellie’s new hair color? Vote in our poll below, and see all news, photos and more from the CMAs!

Demi Moore might be the not-so-secret inspiration behind — and face of — the Helena Rubinstein fragrance All You’ve Ever Wanted, but at the U.S. launch event for the scent in New York, the actress tells WWD that the relationship won’t end there. Demi reveals that she is in a “very deep and serious conversation” with the beauty brand about “giving me an opportunity to create my own line.” Although the star didn’t elaborate about what the line will encompass, she did talk about what motivates her to want to continue her role with Helena Rubinstein. “I feel like I have a greater creative opportunity in working with something where we could really form a true partnership and be really mutually beneficial,” she explains.

Juggling a shapely perfume bottle in each hand, Pamela Anderson, launched her much-anticipated first fragrances Malibu Blue and Malibu Pink in partnership with International Beauty Brands at the W Hotel in Fort Lauderdale, Fla. last night in signature sexy style. “Both fragrances are fresh, chic and luxurious — and totally inspired by the Malibu surf lifestyle that I love,” the former Baywatch babe told PEOPLE. “They are all-natural and embody my free spirit and passionate, ‘get in trouble’ side. Plus, the line is so affordable!” And cost was key for the actress, who wanted the products to be available in drugstores across the nation. “I am a drugstore whore,” Pamela continues. “I worship drug stores. You have to pull me out of them. My dream is for every woman to be able to go to her favorite drug store and buy an affordable fragrance which will make her feel sexy.” And the PETA advocate also made sure that the scents fit with her animal-friendly lifestyle. “Once we completed the product — the glamorous bottle, and the pink and blue packaging — and we were assured everything was ecologically perfect and cruelty free, I was ready to go for it,” she says, adding that a portion of proceeds will benefit the animal charity. Malibu Blue, which contains notes of wild berries and white florals, and Malibu Pink, which combines sandalwood, caramel and vanilla bourbon, range in price from $39 for a 1.7 ounce to $49 for a 3.4 ounce spray, and are rolling into stores now.

Go behind-the-scenes on Usher’s new VIP fragrance campaign, shot in Los Angeles at the Sunset Towers by famed fashion photographer Mario Testino. “I consider fragrance to be one of the most important tools of engagement for seduction. With Usher VIP I created a gentlemen’s scent, which would also appeal to women,” said Usher, in a release. “Women tell me they love the scent of a man and I wanted to create that sense of confidence and style that women desire.” Usher added that his VIP fragrance is “a state of mind which is about what you do with that confidence and how you make an impact in the lives of those around you.” Usher VIP arrives in stores just in time to build anticipation for the artist’s new album release in early 2010.

Moviegoers may be taken aback by Mariah Carey’s decidedly glammed-down turn in the film Precious as a dowdy social worker, and the singer herself had an even stronger reaction the first time she looked in the mirror. “I felt completely rancid!” Carey told PEOPLE at the film’s premiere at the AFI Audi Film Festival. But because the novel that the movie is based on “changed my life,” she gave herself over to director Lee Daniels’ vision for the character’s un-made-up look. “He said ‘We have a part and we really need someone, and I know you can do it,’” the singer explained. ‘”But you’re going to need to let me make you under and over and over again, and that’s what we’re gonna do.’ So I’m a big fan of Sapphire and the book Push which inspired this movie, and a huge fan of Lee Daniels so I let him do what he wanted to do.” Although it took time to adjust to the lack of grooming, Carey said the look helped her achieve a performance that’s now garnering glowing reviews. “I didn’t have to feel compelled to be always glamorous. With the music industry, it’s very like ‘Oh, she’s got a hair out of place! Go fix it!’ You know what I mean? And so this was such a liberating experience and yet humiliated me. But I needed that. We all need that. We all need to understand how to be humble, and it’s a difficult business to do that in.” And now that she’s back to her usual high-glam self, Carey’s moved past the trauma of the first glimpse in the mirror. “I’ve gotten over it,” she laughed, before turning to her husband Nick Cannon for some reassurance. “Have I gotten over it? “A little bit,” he grinned, telling reporters he had no problem with his wife’s makeunder. “I love her in every look — always!” –Scott Huver
