Chris Brown dumped Rihanna because she was too dramatic.
The Fine China hitmaker - who is still on probation for beating Rihanna up in 2009 - reportedly called time on his relationship with her and got back together with his ex Karrueche Tran because he was sick of the drama with Rihanna, 25.
A source told HollywoodLife: "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."
Chris, 24, also prefers Karrueche because she isn't jealous when he talks to other women.
The source added: "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.
