Amber Valletta

Julianne Hough donned a bright red Carolina Herrera number to step out for the EIF's Unforgettable Evening event in support of the Women's Cancer Research Fund at the Beverly Wilshire hotel in LA last night. She was joined by a host of other stars for the charitable evening, including Kylie Minogue, Chelsea Handler, Rita Wilson, Amber Valletta, Angie Harmon, and Lisa Kudrow. Big names from the fashion industry like Carolina Herrera, Tommy Hilfiger, and James Ferragamo were also in attendance for the night out. Funnygirl Chelsea, who was accompanied by her boyfriend, André Balazs, was the life of the party as she made the rounds on stage and visited different tables throughout the dinner. Julianne and Chelsea are not the only stars to support the cause. Next weekend, Halle Berry and Julie Bowen will be among other A-listers to step out for the EIF's Revlon Run/Walk For Women in LA, which benefits women's cancer research.

Aside from her big night out, it was a relaxing week for Julianne, who joined pal Nina Dobrev in Miami over the weekend. Julianne and Nina donned bikinis for a relaxing beach getaway that included fun in the ocean and poolside lounging. Nina has been a supportive friend to Julianne, who broke up with Ryan Seacrest back in March, and the girls turned up at a Lakers game together right after Julianne's publicised split.

Booking a Prada campaign is pretty much the pinnacle of any model's career (if you're not on the Victoria's Secret bandwagon, that is), so we're happy to see that the Italian fashion house is sharing around some of the Spring/Summer '2013 love this season with an A-list ensemble cast. Miuccia Prada favourites Amber Valletta and Raquel Zimmermann return for S/S '13, and familiar faces Sasha Pivovarova, Saskia de Brauw and Kirsten Owen pop up too. The names to note however are the newbies; Vanessa Axente, Irina Kravchenko, Sung Hee, Irene Hiemstra and Maartje Verhoef. These girls are mixing it with some of the industry's best, and for Prada no less. Step inside to see this all-star do their thing for Mr Steven Meisel's expert lens.

Unsurprisingly, the British Fashion Awards drew an incredibly dressed crowd in London today. The official gongs went out to our new favourite face Cara Delevingne (in Burberry) who was named Model of the Year, Stella McCartney who nabbed both the Designer of the Year and Designer Brand of the year titles, while Alexa Chung took home the publicly voted British Style Award. Erdem was honoured with the New Establishment Award and Sophie Hulme picked up the Emerging Talent Award for accessories. On the frock front there were some clear winners. Our top points go to Chanel model/muse Edie Campbell who looked peachy keen in Christopher Kane, Rita Ora who shone in Vivienne Westwood and Pixie Geldof in scarlet satin. Get a good look at who wore what at for fashion's night of nights in London-town. . .

Dark lipstick is definitely having a moment. Sexier than your classic red or flirty pink, it's fast becoming the go-to colour for red carpet glamour. Jennifer Lopez picked a deep berry for the premiere of What to Expect When You're Expecting earlier this week, Rooney Mara is rarely seen without her gothic purple pout and a bevy of beauties rocked up to this year's Met Gala sporting everything from rich chocolate brown (Camilla Belle) to lustruous berry (Amber Valletta and Lana Del Rey). But if you're feeling daunted or uninspired by the colour choice, take lead from these five stars.

The Costume Designers Guild Awards was the latest in a line of award season events to draw a stylish celebrity crowd. In honour of films' crafty costumers, celebs like Rooney Mara, Kate Beckinsale, and Amber Valletta turned to their chic sheaths and pretty dresses to suit up for the occasion. Kate Beckinsale had the night's most glamorous appearance in a romantic Vivienne Westwood floor-length gown, but otherwise these leading ladies, like Rooney in a sweet-cum-sexy J. Mendel frock and Amber Valletta in a brilliant minimalist sheath, showed a little more restraint on the red carpet (perhaps saving their sequins for the Oscars?). Click through to get a glimpse of all of the night's big arrivals — then be sure to tell us your pick for best dressed in the comments.

We're used to seeing the stunning Amber Valletta looking fresh-faced on the runway or red carpet, but she gets dramatically aged in a new editorial spread for the September issue of W magazine. Shot by Steven Klein for "One For the Ages," Amber transitions from a young woman with flapper curls and Clara Bow-esque brows in the 1920s right through to modern day times with some eerily realistic makeup and prosthetic work to age Amber. Thoughts?

Chanel sure knows how to pull a stylish crowd, and an eco-conscious one at that! The French fashion house hosted a benefit dinner for the Natural Resources Defence Council's Ocean Initiative in Malibu, and the A-list were on hand to help. The well dressed crowd flaunted their Chanel loyalty, with loads of signature CC styles on show! From Rachel Zoe's navy tweed, to Courtney Cox's chic shift, to mum-to-be Kate Hudson's elegant black sheath it was all systems Chanel. To borrow from Ms Zoe — we die! Get your dose of A-lister style, here.

The Critics' Choice Awards were a celeb-fest indeedy, but it seems that one star-filled event wasn't enough for the party people! W Magazine was happy to oblige with their post-party at The Chateau Mamont in LA. The stylish celebs did a switcheroo for the after party, with Black Swan cutie Mila Kunis, Amy Adams, Olivia Wilde and always stylish Diane Kruger all slipping into high-shine party ensembles for the occasion.
