Golden Globes: Charlize Theron, Tilda Swinton toast performances

In the penthouse of the Chateau Marmont -- where the routine performances are those of service, fame and occasionally CPR -- W magazine toasted its Best Performances issue just ahead of Sunday's Golden Globes telecast.

With the luminous faces of Charlize Theron and Brad Pitt (the issue's cover stars) adorning the walls, crowds of movie stars, directors and executives floated over Sunset Boulevard mingling with each other and editor in chief Stefano Tonchi.

Theron rocked a lacy black dress and chatted up her "Snow White and the Huntsman" costar Chris Hemsworth -- who sported his "Avengers" platinum blond hair beside wife Elsa Pataky.

Tilda Swinton, rather stunning in a tapered white suit, greeted Tom Cruise, Viola Davis, Patrick Stewart and Jared Leto while monitors played clips of 2011's busiest thespians, including Carey Mulligan.

Orlando Bloom and Miranda Kerr roamed hand-in-hand, Bloom stopping to embrace "Elizabethtown" costar Kirsten Dunst and English breakout actor Benedict Cumberbatch.

Jessica Biel, rumored to be engaged to Justin Timberlake, showed with an empty ring finger but a stunning floor-length sequin gown. She stuck close to a female pal and shared some laughs and a few glasses of Dom Perignon with Kate and Laura Mulleavy, the design duo behind label Rodarte.
