Chris Brown reportedly ended his relationship with on-and-off-again girlfriend Karrueche Tran, who got caught flirting with his one-time enemy Drake.

HollywoodLife recently reported that the "Loyal" hitmaker simply did not trust the model even before their split. "He found out she was texting and sending photos to other guys while they were together," a source claimed.

Also, Tran was apparently using Brown for publicity, promoting her clothing line "The Kill" that they actually created together. "She did press interviews while they were together for her clothing line. Turned out, she was a bit of an opportunist," the source continued. "Chris is done with Karrueche and that's the real reason he didn't bring her to St. Tropez."

"He loves her, he really do, but he can't deal with her and the honest truth is, sorry, but he doesn't trust her. He just doesn't," the source added.

Moreover, when Tran learned that the R&B singer was about to break up with her, she started flirting with Drizzy, according to MediaTakeout. However, the "Nothing Was the Same" rapper was honest with his new friend and showed Brown all the text messages that he had been receiving from her.

"Karrueche got a new manager and started changing up. In the beginning, she was just a cool chick that liked to hang out and have fun," a friend of Chris Brown's said. "Now, she was trying to use every opportunity to make money. Chris did not approve."

"Kae started texting Drake and flirting. She thought that since he and Chris had issues, that he might be open to date her [just to piss Chris off]," the insider revealed. "Drake immediately forwarded the texts to Chris and told him exactly what Karrueche had done. Chris Brown immediately dropped that heaux."
