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 organised 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 favourite 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 Monday at the Academy Awards ceremony.
