Yes Chris Brown Is back with ex girlfriend, Karrueche Tran

It seems so. Weeks after breaking up with on/off girlfriend Rihanna, Chris seems to have moved on to Karrueche. Not only did he spend his birthday with her, he was also spotted making out with her at the Billboard Music awards after-party in Vegas on Sunday night.

The reconciled lovers were photographed yesterday Tuesday May 21 in Los Angeles (photo above) after the car they were riding in rear-ended another car.
