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.

If only the Academy Awards could bring out better celebs (insert appropriately ironic sound effect here).

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.

Maggie Gyllenhaal chatted on the balcony with Topher Grace, while a newly single Ryan Phillippe bobbed and weaved through a crowd that also included Joaquin Phoenix, James Cameron, Emile Hirsch, Ben Silverman, Rosanna Arquette, Matt Dillon and Guy Oseary. 

Madge, clad in a silver top and black fur-lined coat, hit it off with "Star Trek" and "Heroes" star Zachary Quinto. The two were so chummy they carried their lovefest from the balcony to a table inside.
