Chris Brown was reportedly dumped by on-and-off girlfriend Karrueche Tran over Rihanna and his partying ways.

Tran apparently was furious to find out that Brown "liked" two fan photos of him and the Barbadian beauty together on Instagram. However, this was only a small part of her issues with him.

According to TMZ, the sources claimed that the 26-year-old model was actually unhappy to be in a relationship with the 25-year-old R&B singer for quite a while because "Chris acts immature, like a child." Moreover, she said she thinks he is ruining his life by wasting time on partying rather than focusing on his music career post-jail.

Brown reacted to the couple's recent breakup by going on a vacation this week in Saint-Tropez with a bunch of girls, including a good friend of Tran. He was spotted enjoying his time with her on a yacht, making sure Tran sees it.

The "Loyal" hitmaker also took his Twitter account on Thursday, July 31, to write a series of subliminal messages toward The Kill designer.

"Be careful who u take relationship advice from. Especially if they are single. They're single for a reason! Lol #lonelyfacea-s," he began. His continued his social media rant with "Everything is mental," followed by "These hoes ain't loyal but my fans damn sure are!"

However, Karrueche Tran did not respond with jealousy. Instead, the sources revealed that "for safe measure, she changed her number" so that Chris Brown would not be able to contact her. In addition, she recently opened up about how she had been hurt by the infamous love rivalry with the "Diamonds" singer in her emotional interview with Keke Palmer on BET.

"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, do you know what I'm saying?" she said. "But in this case, my boyfriend is a celebrity whose ex-girlfriend is even bigger ... So, not only am I fighting a battle with her, I'm fighting a battle with her 14 million fans or however else."
