The Chris Brown and Karrueche Tran breakup and makeup drama is now over! The couple has finally split up for good, with Chris breaking up with Kae after he found out about "other guys" she was flirting with and realized she was using his publicity for her clothing line!

After all the melodramatic saga that is Chris Brown and Karrueche Tran, the couple has finally split. The two have gone through a lot together, including Chris' jail sentence, breakups and candid interviews.

"He found out she was texting and sending photos to other guys while they were together," a source said.

Chris and Kae were madly in love during the course of their relationship. Even after the Rihanna drama and Chris going to jail, the two managed to get back together every time. They've even created a clothing line together called The Kill. However, now it seems that things are pretty much over. And it looks like Kae has been using the new line to get "in" into the celebrity world.

"She did press interviews while they were together for her 'clothing line,'" the source shared. "Turned out, she was a bit of an opportunist."

Chris discovered Karrueche's betrayal and that ended everything. The "Loyal" singer has been vacationing in St. Tropez solo since the breakup. "Chris is done with Karrueche and that's the real reason he didn't bring her to St. Tropez," the source said. "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 singer is planning to stay focused on his upcoming album right now. X is set to be released on Sept. 16 and it looks like it's going to be a sure hit. Too bad Kae couldn't ride that skyrocket to fame any more!
