You might call it a chronic problem and I’ll agree with you.

Troubled singer Chris Brown was spotted cozying up with a mystery woman Saturday night, days after he admitted he was worried his on-and-off again girlfriend Rihanna would cheat on him while touring.

Brown was partying at the Playhouse nightclub in Hollywood Saturday night and was caught holding hands with the blonde clubgoer. He even gave her a full bottle of Armand de Brignac champagne.

Witnesses said Brown and his posse left the nightclub with a few girls in tow and piled into two vehicles.
