Chris Brown Can’t Keep His Pants On

Karrueche Tran didn't dump Chris Brown because of the girl he allegedly banged in rehab, sources close to the model tell TMZ. She reportedly ended their relationship because the ex-boyfriend of Rihanna (Chris) refused to stop texting his army of jump offs.

There's been speculation that Karrueche pulled the plug when she found out he had hooked up with another girl in his facility at the beginning of March – but TMZ has learned that the break-up preceded that. She reportedly ended things after she visited Chris in rehab the month before.

Sources told TMZ that Karrueche saw Chris' phone during her visit – and it was filled with inappropriate texts from other girls.

Karrueche was especially pissed because she'd been nothing but supportive to Chris throughout his ordeal, even going to court with him.

TMZ was told that Karrueche wasn't even aware Chris had allegedly been getting down with girls in rehab until long after the break-up.

Chris Brown was kicked out of a Malibu rehab center on Friday, and landed in LA jail over the weekend.

Brown has done little to change his image since his 2009 physical abuse of Rihanna. He pleaded guilty to hitting her.

Meanwhile, Rihanna has moved on with singer Drake.
