Karrueche Tran Single: Cheating Scandal, Chris Brown Break-Up Official? Model 'Used' Rapper & Flirted With Other Guys, Breezy 'Missing' Rihanna After Split?

Apparently, Chris Brown and Karrueche Tran are officially over!

Initially, the troubled "Fine China" crooner started ignoring his on-and-off again girlfriend, leaving rather cryptic messages on Twitter and vacationing with a slew of other beauties. But is 26-year-old Tran really the one to blame for the split?

According to an alleged HollywoodLife.com insider, yes. Breezy supposedly caught Tran "flirting" with other guys via text message, and that's when the relationship really started to crumble.

"He found out she was texting and sending photos to other guys while they were together," the snitch reveals.

Was Tran ever really "in love" with 25-year-old Brown, or was she just using him to help further her own blossoming career in Hollywood?

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

Remember, Breezy helped Tran launch her very own fashion brand, The Kill. 

Now that Brown knows that Tran isn't truly "loyal," he's done for good.

"Chris is done with Karrueche and that's the real reason he didn't bring her to St. Tropez," the source concludes. "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." 

And now, the "Wall to Wall" singer's ultimately missing ex-girlfriend, Rihanna.

"It's sad, but the only one he ever really trusted was Rihanna and that's because she didn't need sh*t from him," another HollywoodLife insider claims. "And Saint Tropez, you know that's he and RiRi's most favorite spot in the entire world... He's probably really got Rihanna on the mind. All I'm saying is that he used to always talk about his time with Rihanna there in Saint Tropez. Too many memories with Rihanna there and on that yacht." 

Tran remains mum about the rumored break-up on both Twitter and Instagram. But will things ever work out for Breezy's love life?
