(Cover) - EN Showbiz - Chris Brown's girlfriend Karrueche Tran reportedly "had enough" with the R&B singer.

Throughout the pair's short relationship Chris has been hooking up with other girls.

The crooner has also been openly flirting with his ex-girlfriend Rihanna in recent months. Chris and Rihanna exchanged a kiss at the MTV Video Music Awards (VMAs) in September and reportedly made out in public at a New York City nightclub this week.

Karrueche cannot stand the philandering.

"Karrueche finally had enough and dumped Chris for good," a source told Radar Online.

"Karrueche and Chris had been on thin ice for a while, but after he was spotted getting with Nicole Scherzinger in a Los Angeles nightclub recently, and then when reports surfaced that he had hooked up with Rihanna - so she finally dumped him."

"Karrueche was very patient with Chris and never nagged him about what he had been doing whenever they were apart. She never went through his cell phone, but she suspected for a long time that he had been cheating on her for some time, she just never had the proof.

"They are both young, but she just couldn't tolerate being publicly humiliated anymore." (C) Cover Media
