Chris Brown celebrated his 34th birthday yesterday at Skate Rock City in Las Vegas.

Usher hosted the surprise bash and sang to Brown.

Shortly after that, things went left.

Brown, who was said to be quite drunk, began talking rudely to  Teyana Taylor.

Usher confronted Brown about his behavior.  This angered Brown and Breezy and his crew ultimately gave Usher a beating that left him with a bloody nose.

Happy birthday, indeed.
