Chris Brown back with Karrueche Tran?

Singer Chris Brown has reportedly broken up with R&B star Rihanna again because he was tired of the "drama" surrounding their relationship. He is now said to have reunited with his ex-girlfriend Karrueche Tran.

"Karrueche isn't all hype and crazy like Rihanna and that's probably why Chris chose her in the end. She's drama free and real and she's a good girl," contactmusic.com quoted a source as saying.

Brown, 24, also reportedly prefers Karrueche because she isn't jealous when he talks to other women.

"She loves him and she was even cool with him being with Rihanna while they just kept their relationship on a business level. She was fine with that but in the end, Chris came back to her. She didn't force a thing," the source said.

"Karrueche isn't upset with Chris. Not in the least. She's out in New York having fun and enjoying with him, the city and the nightlife. She knows how many girls want to be next to Chris.

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

The "Fine China" hitmaker is still on probation for beating Rihanna in 2009.
