Rihanna vs. Karrueche Tran Beef Sparks Chris Brown Meltdown: Ex-Girlfriend Furious, Chrianna Love & Lies Break-Up Scandal Exposed

Apparently, Chris Brown lied to (ex) girlfriend Karrueche Tran (again). The "Loyal" crooner still had strong feelings for Rihanna even when he first started dating Tran. And now, there's no chance that the aspiring model will take him back for good!

The troubled relationship (which started back in 2011) was doomed from the start. An alleged HollywoodLife.com insider reveals:

"Chris is mad at himself for going off on Karrueche like that. He acted on impulse and wishes he didn't, but what's done is done, and he apologizes... But the thing that bothers Chris the most is that Karrueche acts as if she didn't know what she was signing up for from the jump."

The source continues:

"Karrueche knew all about Chris' lifestyle when she first met him. He told her straight up that he likes that rock star life in every sense. She also knew that he was still madly in love with Rihanna when they first met, but did Karrueche care? No. Did she care about Rihanna's feelings? Nope. She wanted Chris just as much as he wanted her and she didn't care what woman's toes she stepped on."

But still, the 27-year-old Instagram beauty is now even more furious with her former fame. The lies just keep building!

"When Karrueche first got with Chris, he told her that he and Rihanna were over," another snitch tells HollywoodLife. "He told Karrueche everything a girl wants to hear - how beautiful she is, how much he cared about her and wanted to get to know her and her mind, how he didn't want it to just be about sex - all of that. Chris mislead Karrueche from the get go... He made her fall in love with him. She doesn't regret that. But now, she sees Chris for who he really is: a lying, manipulative little boy who shows no signs of maturing."

During all of this, the "FourFiveSeconds" songstress was still always in the picture:

"She felt it in her her gut all along, but he was so smooth telling her everything to the contrary. There were times when he was so obvious with it. He'd be texting back and forth with Rihanna, but Chris told her it 'wasn't anything serious.' He was a little disrespectful because one time when he picked her up, he had one of Rihanna's songs blasting in the car. Even worse - Rihanna still had clothes and personal items at Chris' house," the insider thoroughly explains. "In hindsight, these were little clues she should have really focused in on. But it became crystal clear to Karrueche years ago, when they had a big breakup in 2012, and he just so magically got back together with Rihanna. Karrueche should have been done with Chris then. But, she kept drinking the juice he was giving her. This time, however, her stomach had enough!"

So, the bitter feud between Tran and RiRi continues - and all because of a guy!

And Breezy can't handle the drama anymore. The hip-hop superstar's extremely upset that he messed-up with Tran. The thought of her with another guy drives Breezy totally crazy:

"Chris is livid and he is feeling various emotions as he is still in love with her," yet another HollywoodLife source claims. "He usually is in control. Karrueche has now taken control and he doesn't know how to handle it. He's having a meltdown."

But did he ultimately feel the same way about Rihanna so many years ago?
