While rumors of Chris Brown and long-time girlfriend Karrueche Tran breaking up have been plentiful as of late, TMZ is now reporting that Tran has officially dumped the "Loyal" singer for a number of reasons. Apparently, the R&B star "liking" ex-girlfriend Rihanna's fan photos on IG was the last straw.

Sources told TMZ Karrueche is also unhappy with Brown's behavior, saying "Chris acts immature, like a child. She thinks he's ruining his life by spending more time partying than making music."

Brown, meanwhile, is living it up in St. Tropez and brought along one of Karrueche's girlfriends for the trip while leaving her behind. Rather than lashing out, Tran allegedly changed her phone number so that Brown can't reach her.

Check out flicks of Brown, Karrueche & Riri above. Do you think they're done for good or is this just another break for the couple? Sound off below.
