Halle Berry, Olivier Martinez, Anne Hathaway, Gerard Butler and More at Dior's 2011 Oscars Dinner

Hollywood's exciting run-up to the Oscars continued with a dinner thrown by Harvey Weinstein and Dior at Chateau Marmont in LA yesterday. The brand's newest model and Academy Award nominee, Natalie Portman, couldn't make it since she was busy travelling to the West Coast with her fiancé, Benjamin Millepied, but plenty of other stars came out to celebrate. It was Halle Berry's second glamorous event of the week after she donned a hot red dress for the Costume Designers Guild Awards, though this time she made it a date night with boyfriend Olivier Martinez by her side. Hostess-to-be Anne Hathaway took a break from her show preparations for the evening out amid rumours that she and James Franco will perform a song from Grease on the stage. Busy Philipps posed with pal Rosario Dawson, while actors Gerard Butler and Adrien Brody took a minute to chat. Ginnifer Goodwin, Jennifer Meyer and Michelle Trachtenberg were among the other guests to toast the upcoming Oscars.
