had a girls' night out at West Hollywood's Chateau Marmont
. The supermodel looked radiant in pants and long sleeves as she enjoyed her friends' company. But the ladies called it an early night, closing out their tab by 9:30 p.m. Also at the Chateau (briefly): Nicole Richie
, who sipped water and skipped food during a quick night out with pal Hayden Slater
. The duo looked immersed in conversation, and left after only 25 minutes.
