Stars descended on the Chateau Marmont in LA last night for W magazine's annual Golden Globes party celebrating their Best Performances issue. Jennifer Lawrence was a bright spot in the night, wearing a blue number after attending the AFI Awards in a colorful Prabal Gurung dress earlier in the day. Globes nominee Marion Cotillard chose a printed look from the same designer for the publication's bash, where Sienna Miller, who is up for an honor at Sunday's show, made her first award-season appearance. She arrived on the West Coast with daughter Marlowe earlier this week and will be hitting the carpet for tomorrow's big event. Also on hand to toast W's latest glossy were Amy Adams, Bradley Cooper, Miranda Kerr, Rachel Zoe, and many more.
