It has been revealed that Chris Brown was dumped by his on-and-off girlfriend Karrueche Tran, even before his alleged inappropriate contact with a woman at the rehabilitation center, for reportedly texting other women.

In addition to being caught violating the facility rules, Brown reportedly bragged about violence and guns, which got him kicked out, sending him to the Men's Central Jail in Los Angeles.

Tran allegedly broke up with the X singer in February after going through his phone while visiting him at rehab. "Karrueche saw Chris' phone during her visit -- and it was filled with inappropriate texts from other girls. It was the last straw," a source said. "We're told Karrueche was especially pissed because she'd been nothing but supportive to Chris throughout his ordeal, even going to court with him."

Texting other women has been an issue for the 24-year-old troubled singer in the past as well, leading to his first publicized split with former girlfriend Rihanna back in 2009. The couple started arguing over Brown receiving texts from another woman, and the fight turned physical and abusive, leaving the Barbadian singer with serious facial injuries, full of bruises.

Chris Brown currently remains on probation over the assault, and his numerous violations of the probation are what led to his recent incarceration. He still has 750 hours of community service to complete.
