Chris Brown Karrueche Tran break up news have resurfaced, and reports say that the R&B star's ex girlfriend Rihanna caused the rumoured split.

According to a report from TMZ, the relationship of Chris Brown and Karrueche Tran ended bitterly after the "Kiss Kiss" singer "liked" Instagram photos of Rihanna.

The said pictures were black-and-white photoshopped images of him and the Barbadian singer lying together on a bed. The two had dated on-and-off since 2008.

The Instagram photos were originally posted on the account @mzfamebreezy last Sunday.

Chris Brown's current girlfriend Karrueche Tran was not pleased, and the 25-year-old model-singer allegedly changed her phone number to finally get away from her boyfriend. She reportedly said the singer "acts immature, like a child" and is allegedly "messing up his life by focusing more on partying than his career".

Chris Brown and Karrueche Tran's break up news follows the latter's recent emotional interview on the talk show "Just Keke".

During the said interview, Karrueche Tran could not hold back her tears when asked about Chris Brown and all the attention she has gained from dating the R&B star.

"I've never dated a celebrity before, so it was very new to me. Paparazzi and all that," Karrueche Tran said.

"And then, even the situation with Rihanna, you know the reason why people tuned in to this so much was because it's relatable. I have girlfriends; I have family who've gone through the same situation. It's the case of the ex. We all go through it, do you know what I'm saying?" she explained.

Karrueche Tran confessed: "In this case, my boyfriend is a celebrity whose ex-girlfriend is an even bigger... So, not only am I fighting a battle with her, I'm fighting a battle with her 14 million fans."

As news of the Chris Brown and Karrueche Tran break up continue to spread, a report from The Hollywood Gossip said the R&B singer has gone to St. Tropez and brought along a very good female pal of her most recent ex-girlfriend.

While there, he has allegedly hosted a party and was photographed hanging out with girls on a yacht.
