She’s a California Gurl with a heart-shaped dress — and a pretty big heart, too. Katy Perry is one of many stars joining forces with eBay for eBay.com/celebrity, a new portal where memorabilia-seekers can bid on amazing experiences and items, all to support a variety of worthy causes.

Perry, one of the first to pop up on eBay.com/celebrity, is auctioning a dress worn on her California Dreams tour: a red-and-pink Swarovski-studded cotton candy pouf, which she’ll give to the winner during a backstage meet-and-greet before her Nov. 21 concert in Oakland.

Angelina Jolie is once again putting her celebrity power to good use, this time lending her glamorous and elegant touch to a charitable jewelry collection. The A-list actress has teamed with jeweler and former Asprey CEO Robert Procop of Robert Procop Exceptional Jewels to design jaw-dropping pendants, rings and more, all centered around statement stones. “Angelina has very classic style. These are pieces she wears herself,” Procop, who has been designing pieces for Angelina for the past decade, tells WWD of  the collection. Angelina even wore one of the pieces, a black spinel necklace bezel set in rose gold, to the Berlin premiere of Salt earlier this year. And just like the $10,000 cufflink collection that she and husband Brad Pitt designed for Asprey last year, the proceeds from the latest line will benefit her charity, the Education Partnership for Children of Conflict. While the stunning assortment of exceptional pieces will not be sold in stores, they will be made available privately to Procop’s clients. A holiday gift that gives back to those in need? Sounds to us like the perfect luxe stocking stuffer. –Jessie Goldberg

It looks like Brad Pitt is finally cleaning up his act. The superstar, who started trimming his year-old facial hair a month ago, was snapped on the set of his new movie Moneyball in Los Angeles Monday completely clean shaven! And while Pitt had famously dispelled rumors that he’d been growing the facial hair for a movie role, telling the U.K. newspaper Sun, “It’s boredom. No other reason that that.” It was this new role, as Oakland A’s general manager Billy Beane, that finally led the 46-year-old star to buzz it all off. While we were starting to get used to the rugged look, we’re certainly glad to see Pitt’s shining good looks come out from under all that hair. Tell us: Are you happy that Brad Pitt buzzed off his facial hair? Or did you like the bearded look? Vote!

In case you’re searching for the Father’s Day gift to end all Father’s Day gifts: Renaissance power couple Angelina Jolie and Brad Pitt have unveiled their first men’s design for venerable British jewelry house Asprey. As part of jeweler’s limited-edition Protector collection, Angelina and Brad have designed a pair of diamond cufflinks, available at Asprey stores now. Sharing the same serpent-inspired motif as the rest of the collection (snakes were a symbolic guardian talisman during the actress’s first pregnancy), the 18k white gold cufflinks are encrusted with elegant black diamonds and punctuated with emerald snake eyes. As much a philanthropic gift as a fashion statement, the cufflinks retail for a cool $10,000, with 100% of net proceeds going to the Education Partnership for Children of Conflict (EPCC), a charitable organization co-founded by Jolie. The collection also includes a jewelled ring and bracelets, as well as children’s items like a tooth box and silver egg cup.

It seems like everyone has something to say about the facial hair that has taken over the faces of two of PEOPLE’s Sexiest Men Alive. Brad Pitt’s beard has been growing through the winter, while his pal George Clooney kicked off award season with the new look. Eli Roth, who appears with Pitt in Inglourious Basterds, thinks his co-star’s beard is amazing. “That’s like a professional beard,” said Roth at the Critics’ Choice Awards in Hollywood Friday night. “Only Brad can pull off a beard like that.” Meanwhile, Melanie Lynskey, who appears with Clooney in Up In The Air, says she hadn’t seen his new beard but wanted to check it out. “He’s not going to look bad,” she tells PEOPLE. “He could bleach his hair blonde and he wouldn’t look bad!” Another guy whose looks can’t be diminished by facial hair is Jon Hamm, according to Mad Men creator Matt Weiner. “He can get rid of it and grow it again in an afternoon,” Weiner joked about Hamm, who plays the dapper Don Draper. “I told him that he looks like GI Joe, which is quite a compliment. There’s nothing you can do to make that guy look bad, let me tell you.” Vote now on which leading man wears his facial hair best! – Elaine Aradillas

Johnny Depp appears smiling, tattooed, and bare-chested on the cover of February’s GQ, and even unclothed, makes the magazine’s list of the 25 most stylish men in the world for 2010. In the accompanying article, Barney’s creative director Simon Doonan sums up why, explaining, “Johnny Depp’s a unicorn—a really glamorous, one-of-a-kind eccentric. He wears great man jewelry. He doesn’t shy away from color. He’s always peeking through his amazing hair. It doesn’t matter if Johnny Depp’s lying in a ditch—he’s always going to look incredible.” Despite their completely divergent aesthetics, fellow Brits Robert Pattinson, Russell Brand, and David Beckham all share the style honors, along with Brad Pitt, Jay-Z and Clint Eastwood, who received a special accolade as “Hall of Famer.” The February issue of GQ hits newsstands nationwide on January 26, but in the meantime, head to gq.com for more and vote for your pick for most stylish guy.

When Brad Pitt first grew in his now infamous goatee, we thought surely it was for a part — or just a personal quirk. But with Hollywood’s hottest hunks sporting everything from Robert Downey Jr.’s neatly trimmed goatee to George Clooney‘s silver scruff to Jon Hamm’s full-out beard, we can see now that Brad was really starting a trend! Clearly this crop of stars is so good-looking that even the worst facial hair couldn’t dim their appeal, but we worry for lesser men if this trend continues. Let’s be honest, who doesn’t want to just see these guys in all of their clean-shaven glory? Or maybe that’s just our taste. Tell us: Should these guys keep their beards or do you prefer them clean-shaven?

Angelina Jolie and Brad Pitt have put their creative minds to something new — elegant serpent-themed jewelry! The power couple has teamed with a top British jeweler Asprey to come up with a series of designs for everything from earrings, pendants, bangles, rings to a silver spoon and egg cup. And, like so much of their life away from the cameras, the collection will benefit others. All the net proceeds will go to the Education Partnership for Children of Conflict, to which the couple has already donated $1 million via the Jolie-Pitt Foundation in June 2008. For Jolie, 34, the inspiration for the collection was an obvious one. While she was expecting Shiloh in 2006, she was given a special gift — a protective snake ring. It was seen as a protector for mother and unborn child, and Jolie has come to view the motif as something of a family guardian. “Since then she has seen the snake symbol as a protective talisman for her family,” a source at Asprey tells PEOPLE. The series started out as something for children — 16-month-old Vivienne has already been photographed wearing bangles with the snake motifs– but has developed into the limited edition “Protector Collection” of high end jewelry and other luxuries, which does still include children’s items like a tooth box and silver egg cup. The collection becomes available tomorrow, November 17. –Simon Perry

Brad Pitt‘s new beard may remind some of MythBusters star Jamie Hyneman, but we couldn’t help but be reminded of another hot hunk who’s recently embraced his hairy side — David Beckham! The soccer player has been showing off an awfully scruffy face lately, just as Pitt grows his goatee into a full beard. We think these are two men who can do no wrong, but whose beard is hotter?

Brad Pitt has partnered with beauty brand Kiehl’s to launch their newest permanent addition to their lineup. Kiehl’s new Aloe Vera Biodegradable Liquid Body Cleanser is the brand’s first complete beauty item that is 100 percent eco-friendly including formula and packaging. But don’t get your hopes up for sexy ads of Pitt, though. Unlike other celeb product campaigns, the Kiehl’s-Pitt collaboration will sadly not feature the star’s photogenic likeness in any of the advertising, but Brad did contribute a hand-written note to be featured on the bottle itself. One hundred percent of the net profits from the sales of Kiehl’s Aloe Vera Biodegradable Liquid Body Cleanser benefit JPF Eco Systems, a charitable foundation created by Kiehl’s and Brad to support global environmental initiatives, reports WWD. The new Kiehl’s body cleanser, $16.50 a bottle, is expected to raise at least $1 million for the charity and will be sold everywhere Kiehl’s products are available starting in October. See kiehls.com for store locations.

Nice to know that new dad Brad Pitt’s not too macho to share his Kenra hair products with female co-star Cate Blanchett. While shooting The Curious Case of Benjamin Buttons, “Brad loved the Platinum Silkening Mist, $12″ says the movie’s hairstylist Colleen Balaghan, who used the same product on his bewigged co-star (Cate is a redhead in the film). “I also used the Kenra Daily Provision Leave-In Conditioner, $9, on both Cate and Brad. Whether we are styling their real hair, or their wigs, they both need a light conditioner that will last and keep their hair smooth throughout filming.” Now, did he bring it home for the whole family?

She’s not even a year old (or able to walk) yet, but Shiloh Jolie Pitt is already sporting the coolest kicks! (Are you surprised with such stylish parents?) Out for a stroll in the Big Easy, Brad and Angelina’s baby was spotted in the same classic style of “Old Skool” sneakers from Van’s as Ashlee Simpson, who tied on a pair a week later for a day of shopping in L.A. Available in a suede and canvas combo for adults, $45 and cute, colorful canvas styles for babies, $20, these trendy trainers look cool whether you can lace them up yourself, or not.

Even though they haven’t been a romantic item for years, Brad Pitt and ex-fiance Gwyneth Paltrow are still on the same style wavelength. During his and Angelina’s visit to Frank Lloyd Wright’s Fallingwater, Brad kept warm in snowy Pennsylvania with a millitary peacoat. A few weeks later, Gwyneth buttoned up in a similar black coat leaving a London gym. Peacoats are always fashionable, but both of theirs offer a nice twist on the classic style, with chic epaulets on the shoulders. Here’s a roundup of similar peacoats in stores right now.

We all love Brad’s style –and that he is a concerned dad– so we’re always interested in where he’s picking up his cool, casual clothes. He snagged a couple shirts, including a buttondown from Edun and a henley from Ever, from Lisa Kline Men, which is a fast favorite of other well-dressed guys like Owen Wilson and Jeremy Piven. Lost star Josh Holloway was just in and picked up 575 jeans and an Ever hoodie, (while co-star Evangeline Lilly happened to be cruising Lisa Kline’s womens store down the street). And if you can’t get there in person to shop– and stargaze– check out the great selection on their website (and bookmark it for the guy in your life).

In the October issue of Esquire, Brad Pitt sounds off on issues close to his heart including architecture, music and. . . diaper rash? According to the new dad, “Shiloh’s got horrible diaper rash, poor thing. Same with Zahara when we picked her up in Ethiopa. . . We’ve tried everything — every cream, every salve, every natural product. We haven’t found the the magic ointment. Yet.” We feel bad for Brad and especially for poor little Shiloh, so we’d love your opinions on the best diaper rash treatments out there. Tell us: What diaper rash trick should Brad and Angelina know about? What products would you recommend to them?

UPDATE: Over 1000 readers have thoughtfully given great advice to Brad about how to cure diaper rash — read more about the response here.
