According to TMZ, the Playhouse club in Hollywood didn't want any trouble and had decided that keeping Drizzy out was the best way to avoid a brawl between the rappers.
Chris was reportedly in the club at an anniversary party for clothing brand Popular Demand - and Rihanna was due to join him later in the evening.
Last year the pair were involved in an altercation which resulted in Brown suffering a gash on his chin.
The incident, which happened at the WIP club, was believed to have erupted over Rihanna's fling with Drake.
Breezy and Drizzy are reportedly suing each other over the brawl.
