In Rihanna and Chris Brown's relationship trial, the verdict is in that excessive arguments and fights is what broke up the high-profile pair, reportedly.

According to Hollywood Life, Karrueche Tran had nothing to do with the split, but instead was an innocent bystander. Supposedly, the ex-and-now rumored girlfriend of Brown watched the former hot-and-heavy and hopelessly-in-love couple crumble in reeling from a difficult, rocky past and mistrust issues.

"Whatever happened know that Karrueche did not play a part in that," a source close to both singers told HL. "Her intention was never to break up Chris and [Rihanna] no matter how much she liked Chris."

The source added that Rihanna "hates Karrueche" but she should let go of her anger because Tran did not do anything to her.

Instead, the source puts the blame on both stars' inability to communicate, remain calm and stand by each other. "[Brown] got tired of all [Rihanna's] crazy ways and her controlling mouth," the source explained. "Karrueche says they used to argue a lot and we all know Chris has a temper."

Simply put, the "Fine China" crooner "dropped" RiRi because she was "too wild and crazy for him," summed up the source. But Brown has a bad boy reputation that rivals or trumps Rihanna's bad girl wrap.

But with such a reportedly passionate connection between the two that survived beyond Brown's 2009 physical assault against Rihanna, many fans are speculating that the two will get back together or write a therapeutic song to get out all their feelings.

And supposedly, Brown's new remix of Mario's "Somebody Else" sounds as if its about Rihanna and his regrets.
