Irina Shayk has graced the cover of the US Sports Illustrated's coveted Swimsuit Issue, walked the Victoria's Secret catwalk, and now she'll try her hand at being Avon's global beauty ambassador. In her new role, Irina will be the face of the new-and-improved Avon makeup line launching it later this year, and is set to star in various campaigns internationally. "I'm proud to partner with a company that is dedicated to improving women's lives and making a difference," she said in a statement. "I'm inspired by the millions of Avon Representatives around the world and the passion they have for both beauty and their businesses." The Russian model has already been featured in multiple Avon makeup campaigns in the past, but with this promotion she'll be joining the likes of Reese Witherspoon, who has beenan Avon ambassador since 2007.

When BB cream — or blemish balm — hit shelves, it was revolutionary for women who wanted foundation-like coverage, minus the foundation. Then came CC cream — colour correcting — which met the needs of women suffering from redness or pigmentation problems. Now, there's a miracle cream for our hair. Earlier this year we reported on Katie Holmes's business deal as the face of US haircare brand Alterna, and now WWD reports on one of the first campaigns we'll see her star in — Caviar CC Cream Leave-in Hair Perfector. That's right, a CC cream for hair!

"It’s both a treatment and a styler and works on dryness and uneven texture for all skin types," Joan Malloy, president of Alterna Haircare tells WWD. With ingredients including caviar extract, vitamin C and a marine botanicals; we're excited to see the reviews. To those of you lucky enough to be travelling to the US in June, Alterna Caviar CC Cream Leave-in Hair Perfector will be sold exclusively at Sephora.

Not content to be the gorgeous face of just one beauty brand, model Cara Delevingne has signed on to be the face of Yves Saint Laurent Beauté's new Baby Doll mascara, according to WWD. The new formula, which will premiere exclusively on yslbeautyus.com on March 20, is the latest addition to Yves Saint Laurent Beauté's Mascara Volume Effet Faux Cils franchise. At launch, it will be available in black, blue, brown, and violet.

Cara, who recently walked in the Saint Laurent Autumn Winter 2013 show, appears in the '60s-inspired campaign donning an all-black Saint Laurent by Hedi Slimane ensemble. The single- and double-page advertisement was shot by Terry Richardson, but the model was recently snapped by another famous face. Karl Lagerfeld stepped behind the lens to capture Cara for Melissa Magazine, WWD reports. Cara also recently signed on to be the face of Burberry Body Tender.

Between being named the new face of Aveeno, becoming co-owner of Living Proof, and also having time for a day job, acting, Jennifer Aniston is one busy woman. As her ad campaign for Living Proof starts to make its debut (shown above) in the March issues of magazines at newsagents now, Jennifer gets candid about the importance of a good hair day.

"For me and a lot of girls, hair is a big deal," she told WWD. "There are a lot of greater trials of the world, but ask any girl — it's one of those boxes you check off. If that means having a better hair day, that goes a long way." Considering Jennifer's hair has been a hot topic since her Rachel days on Friends, partnering with a brand devoted to good hair makes a lot of sense. Keep reading . . .

Olivia Wilde has an addiction . . . to changing her hair colour. From jet black to bright blonde, she has just about tried it all, which makes her the ideal fit as a Revlon hair colour spokeswoman. Her experimentation actually started as a pre-teen when she embraced punk style to its fullest. "When I was 12, I started working my way through the Manic Panic line. I went through purple, green, and I really liked blue," she says. "I remember at one point I wanted to do a sunset. So, I wanted orange into red, which is hard to do crouching over your sink."

While Olivia has stayed away from the primary colours as of late, she hasn't lost her love of experimentation. Even her fiancé, Jason Sudeikis, takes note of her sporadic changes. "I really don't go more than a month with the same hair colour," she says. "So he'll tease me and say, 'Honey, it's been a week, are you sure you don't want to change your hair?'"

Allison Williams is showing off her sensitive side as the new spokeswoman for the skincare brand Simple. Allison may be best known for her role as Marnie on Girls, but she's also made an appearance on The Mindy Project, and now she's garnering attention for her amazing (yet sensitive) complexion. "I do have sensitive skin, actually, and it's been really hard to find products that don't make it inflamed, or red or dry, or make it break out," she told People.

She's found her match in the cleansing wipes. "If you're an actress — and in some cases, this goes for all women — the only thing you can control about your skin is what you put on your face at the beginning of the day, and what you do when you take your makeup off," she said. "Otherwise, it's affected by stress, makeup artists, weather, pollution. The great thing about Simple products is that they protect you against those things — you can wipe it all off at the end of the day." If only those wipes could whisk away Marnie's clingy ex-boyfriend, too.

Well here it is, the first, exclusive look at Katie Holmes for Bobbi Brown. The Broadway actress signed on as the first celebrity face of the brand back in September, with Bobbi adding that that Katie "epitomises the modern 'Bobbi woman'". In the first of two images to be used in the campaign, Katie oozes sophistication with a modern-day smoky eye — a beauty look that showcases Bobbi Brown's soon-to-be-released (March) Long-Wear Cream Shadow Sticks, reports Huff Post Style. "I've always been a fan of her makeup, because it’s so easy to apply," Katie said in a statement. "Her colour palettes aren’t extreme, so when I first started wearing makeup it felt comfortable and I didn’t feel like I had too much on, which can happen."
