Chris Brown, Rihanna Break Up Update: Did RiRi Cheat On Breezy? After Chrianna Fight, Brown Sends Interesting Tweet

Details about Chris Brown and Rihanna's surprising break up continue to leak out, and it seems that we may have some new info straight from Breezy himself. After RiRi reportedly called Breezy to blast him about putting their split out there via the radio, Brown wrote a tweet that seems to indicate it was infidelity that ended Chrianna, that the Bajan singer currently in the middle of her "Diamonds" world tour was cheating.

"She's not mine if she's everybody else's," wrote Brown.

The tweet came after the pair were allegedly fighting over Brown's decision to announce the break up via Australian radio station 2DayFM.

 "I'mma do it solo," Brown said over the air, confirming the rumors that he and Rihanna were through."It's always gonna be love. I'm a grown man, just gotta move forward."

"People have differences and people have different wants and needs," Brown added. "At the end of the day she's a young girl. I can't be focused on wife-ing somebody that young... and I'm young too."

According to an insider cited by the Chicago Sun-Times, this didn't sit well with Rihanna.

"She really thought that was a sexist, degrading thing for him to say. Especially after all Rihanna endured after he beat her and all that," the unnamed source said.

The source said Rihanna called Brown and "really blasted him, using language that made it sound like she never will get back with him again - no matter what people think."

Then, Brown sent the above tweet. Obviously, it could just mean that Rihanna is too busy with her world tour to be in a relationship. However, given their history of side squeezes, we're not ruling out another man.
