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 traveling 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 rumors that she and James Franco  will perform a song from Grease  on the stage. Busy Philipps returned from the snowy East Coast  to pose 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 , where we'll be broadcasting live from the red carpet and backstage .
