“He was just randomly taking photos of himself—like lots of them,” said the witness, who watched raptly as the romance between the actor and his lens unfolded. “It was sort of weird. But he seemed to be having a good time.”

Mr. Braff was apparently unaware of the Bungalow policy prohibiting the use of cameras, and was surprised when a bouncer told him to stop. “He was like, ‘Dude, I’m just taking pictures of myself and my friends—I’m not like some weird celebrity-stalker!’” relayed the source. The group left soon thereafter.

Mr. Braff, who has reportedly dated the paparazzi-paranoid actress Natalie Portman, didn’t return calls for comment.
