George Clooney has taken girlfriend Sarah Larson out on the town a lot lately – even to the Academy Awards. But sometimes, a guy needs a little male bonding.

On Wednesday, the actor made it a guys night out with Rande Gerber, hitting up the night club mogul's hot spot, Stone Rose inside Los Angeles's Sofitel.

Looking debonair in black blazers and black shirts, the guys were recognized right away, an onlooker says. But the famous pals didn't mind the attention. Clooney and Gerber chatted with a steady stream of fans, indulging them in conversation – and never turning a single person away.

Later in the night, the twosome moved to a table by the deejay booth – then continued their good time on the dancefloor before checking out around 1 a.m.
