Photos of Diane Kruger, Alexander Skarsgard, Kate Bosworth, Colin Firth, Russell Brand at Weinstein 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 Weinsten's 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 savouring 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 colourful 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 ton's of events over the past few months. Alexander Skarsgard signed autographs while Gwen Stefani posed with Nicole and Joel. There are only a few hours left before the red carpet starts — overnight in the UK — and we'll be bringing you the winners and all the photos first thing tomorrow morning!
