Out of Rehab -- And into Hyde!

British singer Robbie Williams is officially out of rehab, and what better place to mark that achievement than celeb hotspot Hyde?

Our cameras caught up with the chain-smoking pop star as he tried to sneak out the back door of the swanky joint while stuffing his face with some sort of finger food. Robbie, who usually makes his grand exit through the front, thought it would be a better idea if he tried to keep it low key ... nice try!

Also out on the town, former UFC champ Tito Ortiz with girlfriend Jenna Jameson, Brittny Gastineau, "Entourage" star Kevin Connolly, Paris Hilton (of course), Brandon "Greasy Bear" Davis, "V.I.P." star Natalie Raitano, and our new favorite sex tape star, the very hot Kim Kardashian.
