The Dubai International Film Festival held this year's Oxfam charity gala tonight with major Hollywood names like Rooney Mara, Freida Pinto, Kristin Davis, Colin Firth, and his lovely wife, Livia, all stepping out in their finest formal attire. Rooney stuck with her signature slicked-back locks and opted for a sheer and shimmery look from Calvin Klein. Freida chose a vintage red gown from Valentino, while Kristin kicked up her heels in vintage Dior.

The celebration is a reunion of sorts for Colin and Rooney, two of last year's award season favorites. Rooney earned her first-ever nomination for The Girl With the Dragon Tattoo, and Colin took home the Academy Award for best actor for his role in The King's Speech. He'll likely return to the Oscars this year as it's traditional for the previous winners to take part in the show. We're less than a month away from the kickoff of award season, with both the SAG and Golden Globe nominees announced this week!

Colin Firth and his wife Livia teamed up with Anna Zegna, of Ermenegildo Zegna, to host a dinner at LA's Chateau Marmont last night. The evening was organized in support of Oxfam and the Green Carpet Challenge, a cause close to eco-friendly Livia's heart. She frequently blogs and tweets about wearing recycled ensembles on the red carpet, and yesterday's dress was a creation from one of Kate Middleton's favorite lines, Beulah London.

Livia and Colin made the rounds to chat up their fellow Brit Emily Blunt and her husband John Krasinski. The Vanity Fair crew was well represented with editor in chief Graydon Carter and his wife Anna on hand, in addition to West Coast editor Krista Smith and publisher Edward Menicheschi. Other celebs made the rounds as well, including Cameron Diaz, Kristin Davis, Mia Wasikowska, and Emile Hirsch. Gary Oldman, who's up for a best supporting actor Oscar for his work opposite Colin in Tinker Tailor Soldier Spy, dropped in to say hello. He and Colin will reunite Sunday at the Academy Awards ceremony — make sure to fill out a Oscars ballot with your winner predictions and enter to win an iPad.

As amazing as it is to see all the red-carpet arrivals at the Met Gala, we love knowing what goes on behind the scenes before, during, and after the big bash. Whether it was a peek at the primping of Gisele Bundchen, performance pics from Prabal Gurung, or Livia Firth and Coco Rocha tweeting from the ladies' room, the stars — and their cell phones — captured some amazing, surreptitious sartorial moments.

Anne Hathaway celebrated the end of a very successful Oscars hosting gig by hitting the dance floor at the Weinstein party. She grabbed onto someone's little gold man, presumably from one of the many The King's Speech wins, to show off her moves and her arm muscles with the heavy statue. Her boyfriend, Adam Shulman, watched on and joined in on the fun as onlookers snapped pictures with their phones. Anne picked her red Atelier Versace for the festivities, which was one of seven looks she wore on stage. James Franco and Anne's performance earned mixed reviews, and Buzz thinks she could have done it all on her own. James also released the full video of their Grease homage that ended up on the cutting-room floor. He apparently wasn't in the mood to hit the town last night, since he skipped his own ultra-exclusive bash to head back to school on the East Coast.
