Chris Brown is in jail at the moment, but just because he's locked up doesn't mean the hot-tempered singer can't create drama on the outside.
Two of Chris' exes nearly had a run-in last at a Hollywood nightclub.
Karrueche Tran (who may or may not still be dating Brown) narrowly avoided confrontation when she and her friends bolted from the club upon learning that Rihanna had arrived with her entourage.
Reportedly, Rihanna is dating Drake so it seems unlikely that she's still so hung up on Chris that she would start beef with Karrueche.
Even, so RiRi's temper is alomost as notorious as Chris', so Tran and company may have done the right thing by playing it safe.
Besides, maybe Tran wasn't afraid of a physical confrontation and just wanted to avoid partying with her ex's ex. Even semi-celebrities like Karrueche probably hate awkward situations like that.
