Soho House held a preview party Thursday night in West Hollywood, receiving an embarrassment of bold names at its newest venue.
The members-only club, which has outposts already in London and New York, partnered with Grey Goose to open its doors to Madonna, Elton John, Quentin Tarantino, Natalie Portman, Harvey Weinstein, Jennifer Lopez and Marc Anthony, Kellan Lutz, Rachel Zoe, Josh Hartnett, and Clive Owen.
The stars gathered in the penthouse of the exclusive Sunset Boulevard property to celebrate Sunday's big show and raise awareness for RADD, aka "the entertainment industry's voice for road safety." The select, wall-to-wall crowd snacked on steak tartare and Champagne in the redesigned space that the club had rented for a week of sneak-peek Oscars parties in 2008.

And in more Oscar related news, Madonna, her manager Guy Oseary and Demi Moore will stick to what has become a tradition now and will have their after-party going around 11 p.m. in a tent attached to Guy's Hollywood Hills home on Sunday, Variety.com reports.
