Karrueche Tran dumped her boyfriend, Chris Brown, for several reasons, according to reports. One was because Brown "liked" two fan photos on Instagram of him and Rihanna together, and the second reason was because Tran was unhappy.

"Chris acts immature, like a child," a source told TMZ.

The source said the model is worried Brown may be jeopardizing his music career by partying and drinking too much and decided they needed some time apart. So how did Brown respond to the breakup? According to TMZ, he took a vacation to St. Tropez... with a close friend of Tran's.  

The two were photographed on a yacht together, along with other girls. Tran responded to the reported diss by changing her phone number so Brown couldn't get in touch with her. You can check out the photos on TMZ and Media Take Out.

Last month Tran opened up about dating Brown and even cried when she started to talk about their relationship and constantly being compared to Brown's ex, Rihanna.

"I've never dated a celebrity before so it was very new to me, paparazzi and all that," she told KeKe Palmer on her new talk show "Just Keke."

She added that the beef between Brown and Rihanna didn't make things any better.

"And then even the situation with Rihanna. You know, the reason why people tuned into this so much was because it's relatable. I have girlfriends, I have family who's gone through the same situation. It's the case of the ex. We all go through it," Tran said.

"But, however, in this case my boyfriend is a celebrity whose ex-girlfriend is an even bigger [celebrity]... So, not only am I fighting a battle with her, I'm fighting a battle with her 14 million fans. So imagine how that feels for me."

When Palmer asked Tran what was the hardest thing about being stuck in a love triangle with two celebrities, Tran started to tear up.

"I guess I would say the heartbreak... Because it was a real situation," she said. 

Is Chris Brown wrong for reportedly vacationing with Karrueche Tran's friend?
