Rihanna wants Chris Brown to completely end his relationship with Karrueche Tran. The 24-year-old 'Stay' singer has reportedly told her 23-year-old on-again/off-again boyfriend that she won't put up with him continuing to see his model ex-girlfriend behind her back. A source close to Rihanna told HollywoodLife.com: "Rihanna's trying to lay it down hard and she's turning the tables on him." The 'Turn Up The Music' singer is said to have agreed and is already trying to do little things like clean Rihanna's car while she was away recently to let her know he wants to live in domestic bliss with her. The insider said: "He picked up her car, drove it to his house while the homie drove him there and followed him back in his car -- just so he could have it detailed and clean for when she gets back. "He went to her crib and turned on lights and set her alarm. Little stuff like that. Ri can hire people for all that, but he wants to do it for her. He is in it 100 percent right now.”
