Fresh off filming the Victoria's Secret Fashion Show last week in New York, yesterday (Nov. 13) Alessandra Ambrosio was on the opposite side of the country-- Los Angeles, to be exact-- for GQ magazine's "2012 Men of the Year Awards" party at the Chateau Marmont hotel.

The 31-year-old supermodel looked hot as ever in a Sally LaPointe dress.

And she was in good company. Rihanna, Kate Walsh, Seth MacFarlane, Sarah Silverman, Ali Larter, Cassie, Ne-Yo, Rashida Jones, Aziz Ansari and Chace Crawford were just some of the other folks in attendance. In short, let's just say the celebrities definitely came out for this event.
