Hot on the heels of a very public date with his ex Rihanna at the Jay-Z concert, Chris Brown has called it quits with his girlfriend of a year Karrueche Tran.

"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," Brown said in a statement to Us Weekly.

Although he claims he'd rather be single, the "Don't Wake Me Up" singer looks like he's headed for a reunion with his former flame RiRi. Besides their PDA at Hova's show, they were also spotted enjoying a steamy makeout session at NYC hotspot Griffin earlier in the week.

"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," a source told the mag.

Let's hope the heart is the only thing that's beating if these two get back together!
