Recently single Kelly Osbourne snuck onto the patio at West Hollywood's Chateau Marmont with a girlfriend. The starlet was huddled up in a blue-gray jacket and scarf, as she camped out in a remote section of the patio with her pal, picking at some food, sharing drinks and chatting well past midnight.
Also at the Chateau: Jon Hamm, who blew onto the patio to greet a trio of old friends. The three spent hours catching up as Hamm relaxed in his chair, smoked a little and drank some beers.
Rosario Dawson, dining at Katsuya Brentwood with a large group of 12, including her friend Wilmer Valderrama. The group sat in the Dragon Room for almost three hours dining on king crab legs, black cod and crispy rice.
