Chris Brown and Rihanna did not end their relationship because of the singer's ex-girlfriend, Karrueche Tran, according to sources. 

Brown split with Rihanna about a month ago after rekindling their romance after another break-up in 2009, but the two lovers are done for good. 

While many blamed Tran for the former couple's break-up, sources said that Rihanna and Brown fought a lot in their relationship. 

"Whatever happened, know that Karrueche didn't play a part in that," the source said, according to Hollywood Life. "Her intention was never to break up Chris and her no matter how much she liked him."

The source also revealed that Rihanna is not too fond of Tran. "I know that Rihanna hates Karrueche and can't stand her but she shouldn't be so angry. Karrueche didn't do sh*t to her."

While Rihanna has been posting pictures of herself on her Instagram account engaging in wild antics, the source said that Brown soon got tired of the Stay singer's recklessness. 

"He got tired of all her crazy ways and her controlling mouth. Karrueche says they use to argue a lot and we all know Chris has a temper. He just dropped her because she was too wild and crazy for him," the source said. 

Meanwhile, Brown performed at Hot 97's Summer Jam in NYC on Sunday, with Tran by his side. The model socialite was pictured sitting on the stage with the singer performed his set. 

E! News reported that the couple attended the Pink Elephant nightclub on Sunday night and partied with a group of men and women.

While Brown was said to have attended a later party with a mystery woman, sources said that Tran is not worried about Brown messing around with other women.

"In the beginning, when she first met him, she was taken back by all the crazy attention girls gave him, but now she's use to it. They're just a bunch of groupies who don't hold a candle to her," a source said.
