With only four days to go before the Golden Globes, Best Actress nominee Michelle Williams looked more at ease than ever at the Weinstein Company party sponsored by Audi in L.A. Wednesday.

Held at the famed Chateau Marmont, the 31-year-old actress arrived just before 10 p.m. and immediately made her way to the table reserved for My Week With Marilyn. After chatting up studio head Harvey Weinstein, Williams reunited with her Dawson's Creek costar and good pal Busy Philipps, 32.

Though an eyewitness tells Us Weekly Williams "didn't drink anything but water" throughout the evening, that didn't stop the stylish star from having a good time. After briefly chatting up Zoe Saldana's new man Bradley Cooper, Williams happily posed for a fan photo.

Once Williams and Philipps left their table, "Busy was bopping up and down and making Michelle laugh," the eyewitness adds.

Hopefully Williams' bout of confidence continues through Sunday's Golden Globes: she's up against Jodie Foster (Carnage), Charlize Theron (Young Adult), Kristen Wiig (Bridesmaids) and Kate Winslet (Carnage) in the Best Performance by an Actress in a Motion Picture - Comedy or Musical category.
