Apparently Rihanna isn't so trusting after all!

According to a new report the singer wants beau Chris Brown to completely end his relationship with ex-girlfriend Karrueche Tran.

“Rihanna’s trying to lay it down hard and she’s turning the tables on him,” a source said.

Brown 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.

“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,” said the source.

“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 in it 100 percent right now.

“(Chris) told Karrueche it’s done and he can’t kick it with her anymore. It’s done, no more...he likes her and all, but if he’s trying to be serious with Rihanna, he knows it’s got to be over.

“He basically told her...that he’s trying to focus on Rihanna and he needs his space. Chris and KT are always going to have that special connection, but Rihanna’s got him right now and he’s into her. He’s always been into her — it’s just now he’s making her number one. Ri is number one right now.”
