While it looked like things were going well for Chris Brown and Karrueche Tran, it now appears the couple have called it quits -- again. However, the reason why is still up for debate.

Some say that Karrueche has been disloyal to Breezy despite the fact that she's been visiting him while he's in jail and showing her support at his court dates.

But TMZ is reporting that it was actually Karrueche who kicked Brown to the curb. And to make things a bit more final, she's also reportedly changed her phone number.

According to the gossip website, Tran didn't appreciate the fact that Brown has been liking so many of his ex-girlfriend Rihanna's Instagram photos and also saw that he just wasn't growing up.

While neither party (or their people) have confirmed anything, Brown seems to be enjoying his singlehood in St. Tropez. So apparently, the singer's way of grieving is by soaking up the sun and partying on a luxurious yacht.
