Chris Brown has ended his one-year relationship with model Karrueche Tran.

The musician has released a statement explaining that he doesn’t want his friendship with his former flame, Rihanna, to upset Karrueche Tran.

He said: "I have decided to be single to focus on my career. I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna. I'd rather be single allowing us to both be happy in our lives."

The news that he has parted way with Tran comes days after he was spotted at a Jay-Z concert with Rihanna. There are also several reports claiming the pair have enjoyed a number of dates recently.

A source told US Weekly: "Chris really wants to be free to pursue Rihanna now that she wants him back. They will be together, trust me. I always told you he'd go back to Rihanna in a heartbeat when she was ready."
