Michelle Williams and Bradley Cooper at Weinstein Company Party Pictures

Michelle Williams helped the Weinstein Company get a head start on the Golden Globes celebration last night. Harvey Weinstein's enterprise hosted a bash at the Chateau Marmont that brought out the My Week With Marilyn star and her best friend, Busy Philipps. Busy was still in the bright blue Carven dress she wore to the 2012 People's Choice Awards, where she told us about her plans to be Michelle's date to the Golden Globes on Sunday! The girls went together last year as well, when Michelle was nominated, but lost, for Blue Valentine. Busy joked that if Michelle doesn't win this year, perhaps she should consider another date for future award shows!

A mustache-sporting Bradley Cooper also made the rounds at Harvey's party after stopping by Liam Neeson's premiere of The Grey. He said hello to friends at the Chateau like Paula Patton, Jamie Foxx, Jennifer Morrison, Lindsay Lohan, and Downton Abbey's Elizabeth McGovern. We may see many of the same faces this evening on the red carpet at the Critics' Choice Awards — stay tuned later for our live coverage, which starts at 3 p.m. PT / 6 p.m. ET!
