Back of Nominees and Tons of Stars Head Out For Weinsteins' Pre-Oscars Parties! The stars were all over town last night taking in all the Oscars mania, especially at the Weinstein Company's huge parties! The new SoHo House in West Hollywood and the Chateau Marmont were both brimming with celebrities for the Weinstens' charity events for UNICEF. Nicole Richie looked fantastic in blue out with Joel, who is the official DJ of tonight's show. Carey Mulligan says she's savoring these final days of award season but is also ready for it to be over. Kate Bosworth and Diane Kruger stuck with short, sweet, and colorful despite the dreary weather, and we're especially excited to see what the sexy Inglourious Basterds star wears for the Academy Awards red carpet. Diane and Joshua Jackson also stopped by the Chanel and Charles Finch dinner, giving us high hopes that he'll be with her this afternoon. First-time nominees Gabourey Sidibe and Christoph Waltz laughed together after seeing each other at tons of events over the past few months. Alexander Skarsgard signed autographs while Gwen Stefani posed with Nicole and Joel. Even The Bachelor's Vienna Girardi and Jake Pavelka got in on the fun! There are only a few hours left before the red carpet starts, and we're gearing with tons of looks back at iconic Oscar moments and will be covering the main event live all night long!
