As the straight man in the Hangover movies, Justin Bartha is too good looking to be called attainable, but a smidge more approachable than the average Hollywood hunk.

A little out of reach, and with a solid Hollywood dating history (he dated Ashley Olsen for two years before being linked to Scarlett Johansson), the 33-year-old makes for the ideal fashion girl crush. Only one problem: he doesn’t really ‘get’ style.

“I don’t really think about it actually. For me, it’s just about comfort,” he says in a profile on Mr. Porter. “That’s the most important thing. I’m all about fit and fabrication as well.” OK, so maybe he’s not completely clueless.

And though the actor wears an Alexander McQueen jacket, Lanvin sneakers and a $265 Maison Martin Margiela T-shirt in the spread, Bartha values sentiment over designer duds. “I have a golfing shirt that my late grandfather wore,” he reveals. “I absolutely idolized him. He gave it to me and I bring it wherever I go. I wore it on the audition for the first movie I landed.”

We hope he’s not referencing 2003′s Gigli …

After refusing to wear makeup in We Bought a Zoo, Scarlett Johnasson reveals that when she’s not portraying a character, she’s actually quite fond of putting on a face.

“I always like to put a little bit of makeup on,” she tells Style.com. “I’m not the kind of person that just slops around in sweatpants. I like to feel a little more together — you never know who you’re going to see out there!”

“My absolute must-have is a really rich and vibrant red lipstick,” she reveals of the look that has become synonymous with her red-carpet bombshell motif. “I always keep red lipstick in my bag because I never know when I might show up to an event and be completely underdressed. I feel like red lipstick is the cure-all for everything.”

Other things that make her feel beautiful include reverting to her natural hair color (“I’m naturally blonde so I feel most like myself when I’m blonde”) and a good, old-fashioned honey facial. Yup, a honey facial. “I use Manuka honey,” she reveals. “You just warm your face so that your pores are open (you can steam your face right after getting out of the shower), and then you just take a spoon and apply the honey directly to your face and leave it for 10 to 15 minutes.”

The result? “It really adds an amazing glow and your skin is so soft afterwards. It pulls out the impurities.”

LEARN MORE INSIDER TRICKS IN ‘DIY STAR HAIR AND MAKEUP’

At the New York premiere of We Bought a Zoo, Scarlett Johansson’s skin shimmered with glacier-blue shadow and baby pink gloss: a far cry from her character, who shuns the stuff entirely.

To play an animal caretaker alongside Matt Damon in what she calls a “decrepit Grey Gardens of a zoo,” Johansson felt that the audience wouldn’t believe her in the role if she were wearing fake eyelashes and lip plumper. Hence, a strict adherence to a no-makeup policy, she tells Vanity Fair.

And this isn’t the first time the 27-year-old has augmented her looks for a role: Jon Favreau, who directed the star in Iron Man 2, tells the magazine, “Scarlett was not the logical first choice for the Black Widow,” but when she auditioned for the role, “she had red hair. She said, ‘I wanted to show you that I was serious.’

“She’s uniquely beautiful,” he continues. “She’s smart and talented. That’s a tough combo to beat.”

VOTE ON STAR BEAUTY CHANGES IN: ‘WHAT’S HER BEST LOOK?’

Scarlett Johansson is once again proving she’s a pro at creating a dramatic beauty moment! The star, who serves as the face of Dolce & Gabbanna beauty, is stunning in just-released behind-the-scenes images for the new DG Passion Duo lipsticks and Creamy Foundation.

In the glamorous shots, taken last summer in London during a fun-filled photo shoot, the bombshell poses seductively with bright-red lips and flawless skin, wearing a D&G robe and a sexy dress.

Johansson was first announced as the face of the makeup brand in 2009; at the time she was photographed in a series of shots meant to evoke Marilyn Monroe’s iconic beauty.

“Scarlett is a wonderful woman who, thanks to the fact that she is an actress, is able to play every time a different type of woman, or better, different aspects of the character of a woman: sometimes ‘girl next door,’ some others a ‘seducer,’” Stefano Gabbana told PEOPLE this summer.  Added Domenico Dolce, “It’s exactly this thing that we like most in her. She’s like a chameleon, she knows how to play with her image.”

Scarlett Johansson knows how to create a dramatic beauty moment. “If I’m doing a red carpet, I’ll usually look to the golden age of Hollywood a little bit, whether that’s Rita Hayworth or Lauren Bacall or later, like Brigitte Bardot,” she tells Stylelist.com. “I like to kind of give a nod to that era; I feel like the red carpet deserves it.”

Where did that inspiration come from? “My mom was very glamorous,” the face of Dolce & Gabbana beauty shares. “I used to sit at her vanity and use her makeup — I know a lot of moms, they don’t really like their daughters to wear a lot of makeup. My mom was always very encouraging, she used to take me shopping so I learned a lot of about makeup application from her actually.”

But these days, her routine is fairly streamlined. “I have sensitive skin, so I use actually just Cetaphil face wash and Clarins moisturizer,” she says. “I don’t wear a lot of makeup during the day.” Naturally, she carries Dolce & Gabbana makeup — like the Gloss Fusion Lipstick in Infatuation and Poetic, plus the brand’s powdered foundation — but she admits she doesn’t tote too many products in her bag.

However, that doesn’t mean the actress was spared from some questionable makeup trends in her earlier years. Jokes Johansson, “It was the ’90s and I had a lot of blue lipstick, glittery nail polish, glitter eyeliner — I was like a disco ball.”

The word ‘muse’ might be bandied around the fashion world — but for Dolce & Gabbana’s designing duo a relationship with Scarlett Johansson goes beyond clichés. “I wouldn’t say [Scarlett is] a muse, but an interpreter,” Stefano Gabbana explains to PEOPLE of working with the face of the label’s cosmetics line, The Makeup. “Scarlett is a wonderful woman who, thanks to the fact that she is an actress, is able to play every time a different type of woman, or better, different aspects of the character of a woman: sometimes ‘girl next door,’ some others a ‘seducer.’” Adds Domenico Dolce, “And it’s exactly this thing that we like most in her. She’s like a chameleon, she knows how to play with her image.” In her latest campaign, for the Italian Summertime collection (above), she does just that, this time channeling the natural sensuality of stars like Sophia Loren. “We really wanted to create a look that was full of the vitality and sensual perfection of a heady summer day in Sicily,” says makeup artist Pat McGrath. “It was imperative that Scarlett’s skin looked gently sun-blessed and full of healthy vitality,” she continues, “so I blended the Animalier bronzer all over her face, paying particular attention to Scarlett’s cheeks, nose and brow bone. I then applied a light dusting of Luminous Cheek Colour in Sole upwards at the very height of the cheekbone, just where the light would hit the highest point of her face and give her cheeks a beautiful natural color.” The result? Bellissima. –Katherine Kluznik Rentmeester

Scarlett Johansson has never been shy about changing her hair. The sexy star — most recently a blonde — has rocked long brunette locks, light and edgy bobs and even platinum styles. But Saturday night, at the White House Correspondents’ Dinner in Washington, D.C., she shocked us a little with her brand new auburn tresses. Johansson — who left an after-party hand-in-hand with rumored beau Sean Penn — beamed as she walked the red carpet in a greenish-gray Elie Saab dress, the perfect complement to her glowing skin and newly red locks. The actress joins the ranks of other new redheads like Blake Lively and Drew Barrymore. Do we have a hot new hair trend on our hands? Tell us: What do you think of Johansson’s new hair color?

When best actress nominee Jennifer Lawrence descended upon the scene at the Kodak Theatre Sunday night, everything from her form-skimming column dress to her tousled locks struck a chord in viewers’ collective Oscar memories. And it wasn’t that she looked sensational, which she undeniably did, but that the entire look was so very reminiscent of Scarlett Johansson‘s va-va-voom turn at the 2006 Golden Globes. From the décolletage to the platinum mane, the Calvin Klein-wearing newcomer was a dead ringer for a scarlet Valentino-clad Scarlett.

Scarlett Johansson is giving a whole new meaning to the term ‘fashionably late’! The actress waited until a mere four days before this Sunday’s Academy Awards show to be fitted for a dress. But Johansson’s stylist, Nicole Chavez, isn’t worried. “What it comes down to is — may the best dress win,” Chavez told CNN.com. “My goal was to make her feel beautiful, happy and comfortable,” she says of Scarlett, who was asked to present an Oscar two weeks ago, “[to] find the perfect fit.” And when it comes to prepping on the day of the big show, Chavez imagines that it will be a low-key environment, with Johansson surrounded by friends and family, sipping wine and taking pictures. “It’s comparable to a wedding day,” Chavez says. “Everyone will just be having a good time.” —Kim Peiffer

It looks like Nicole Richie‘s not the only A-lister loving the tousled bob. Fellow blonde bombshell Scarlett Johansson turned heads last night when she stepped out at the Mango Fashion Awards rocking the same sexy style. The actress, who debuted her bobbed do three months ago with a bed-head take on the cut, has evolved the look into a shorter, sleeker, more coiffed style, with slightly sculpted waves and turned-up tips.

Scarlett Johansson vamps it up for her newest Dolce & Gabbana The Makeup cosmetics campaign, returning to her screen-siren roots in dark berry lips and a sexy satin ensemble. “We wanted to discover a look that truly reflects our ‘story’ from the very beginning-yet truly reflects our reverence for today’s women, epitomized, of course by the divine Scarlett,” explains Stefano Gabbana of the Evocative Beauty Collection campaign, which features the corseted actress reclining in a sea of leopard print. “It addresses what’s so ineffable about a woman–her fierce sensuality anchored by her innermost femininity,” adds Domenico Dolce. Balancing classic glamour with a vampy edge inspired by the runway, Scarlett’s sultry look will hit select Saks Fifth Avenue locations and saksfifthavenue.com at the end of August, with prices ranging from $20 to $59.

Never mind her enviable bone structure, pouty lips and voluminous hair–or the weeks of hardcore training she endured to get in shape for her role as a catsuit-clad spy in Iron Man 2–Scarlett Johansson chalks up her famous good looks to her glam squad. “Working with these incredible hair and makeup teams, you go in looking like a schmoe, and you come out like a movie star,” V magazine‘s June cover star says. The 25-year-old actress, who despite a busy schedule lighting up the Broadway stage and the big screen has found time to appear in campaigns for Dolce & Gabbana Beauty, Louis Vuitton, L’Oreal and Mango, says, ”You go through the works, and then you’re like this perfectly prepared sausage…no one ever sees what goes in.” Sorry, Scarlett, while we don’t doubt the talent of your stylists and makeup artists, we’d hardly compare you to a link of kielbasa! For the full interview, pick up the June issue of V magazine, on newsstands May 11. –Marissa Patlingrao Cooley

Dynamic special effects, juicy new villains and Robert Downey Jr.’s zippy one-liners aren’t the only compelling reasons to go see Iron Man 2. Also worth checking out are the toned physiques of leading ladies Scarlett Johansson and Gwyneth Paltrow, both of whom endured grueling workouts to get hardbodied for the movie. As part of her role as the Black Widow, Johansson famously dons a skintight Lycra catsuit in the film. “I was very proud to be in the catsuit,” the 24-year-old actress told PEOPLE at the Iron Man 2 premiere at Hollywood’s El Capitan Theater yesterday. “I worked really hard to get there, and by the time I put it on, it was like ‘If I don’t look good in this catsuit now, I should just never wear it. You’ve just got to own it.” And what did the star do to prepare for the unforgivingly snug costume? “Lots of strength training, lots of fight training, lots of stunt training–and lots of pain!” laughed Johansson, who wore a sculptural one-shoulder Armani Prive cocktail dress on the red carpet. For her part, Paltrow, who showed off the results of her tough training in a Giorgio Armani shorts suit at the premiere, logged major hours with her trainer Tracy Anderson before resuming her role as Pepper Potts. “[Tracy] killed me! She kicked my butt!” laughed Gwyneth. And even though Gwyneth doesn’t play a superhero–yet–she still had a good reason to get in shape. “Originally there was a scene–it was like a fantasy scene–and I was in lingerie, and I was so panicked. I thought ‘Okay, I really have to get in good shape.’ And then it ended up getting cut out and I was already in such good shape that I had to keep going,” says Paltrow. Now, with her new rock-hard body, Paltrow sees a superhero role in her future. “I could be an Iron Woman. Iron Woman would work.” Tell us: Are you excited to see Irom Man 2? – reporting by Scott Huver

In the clip, the sultry star sports a skimpy black strapless dress and heels while lounging at a kitchen table and peeling an orange. “It seems simple. Beauty is on the outside, but you might have to get what’s inside to get to what’s sweet. Beauty that’s in your mind — that’s the one,” she says, alluding to the fragrance “L’eau The One.” Buy your own “L’Eau The One” at neimanmarcus.com, $60 for 1.6 oz. –Kristin Larson

She may have recently sweated it out in order to get into the tight cat suit for Iron Man 2, yet Scarlett Johansson still can turn up the glamour factor. This afternoon, the face of Dolce & Gabbana The Makeup popped into London department store Selfridges, on Oxford Street, to launch the line and share a few of her favorite beauty tips.  Greeted by hundreds of fans who had packed the department’s store Beauty Hall, Johannson made a spectacular entrance, Hollywood style to the strains of Shirley Bassey’s classic “Diamonds are Forever.” “Thank you all so much for coming here today, I’m overwhelmed by the amount of personal cameras!”, said a prim and proper Johansson,  who looked every inch the modern incarnation of Veronica Lake. Dressed head to toe in Dolce & Gabbana’s spring summer collection, her strawberry blonde tresses were styled in waves and her trademark lips were painted with the label’s ‘Iconic’ red lipstick. And the star finds her look to be perfectly in sync with the makeup line. “I like the line’s modern classic makeup because I like a modern classic look. When I go out, I always pay homage to the golden age of Hollywood. Dolce & Gabbana make up is a modern classic and the packaging is beautiful too.” How did she achieve that Old Hollywood style make up? By using Dolce & Gabbana’s Perfect Finish Powder Foundation in Natural, the Luminous Cheek Colour in Peach, the Smooth Eye Colour Quad in Nude and the Classic Cream Lipstick in Iconic. And keep checking in with us, as Johansson also revealed that she was in town to shoot an upcoming campaign for the collection.
