After putting on his serious face at the Service Summit in NYC on Thursday, Leonardo DiCaprio shifted his cap to the side and partied it up at 1OAK on Saturday night to celebrate the birthday of the club's co-owner, Richie Akiva. He chatted with Diddy and posed for photos with Usher and his BFF Lukas Haas, who even had a bit part in last night's Entourage, which you all are still loving. Looks like Rachel Zoe is still drinking to her new show you're also fans of, while Emmanuelle Chriqui and Lindsay Price were a couple more pretty faces in the crowd.

I am A-ddicted to the Rachel Zoe show. That reminded me so much of my last job I literally was like biting my nails with excitement. I could Die!
