It has been reported that Chris Brown and Rihanna are officially back together and have recorded a song called ‘birthday cake’. The song which was heard by MTO, has Chrish Brown apologizing for beating Rihanna, and confessing his love for her. There is a twist in the story though. Apparently, Jay Z and Rihanna’s RocNation management is not amused by the song and the project could not see the light of day. The latest developments leave Chris Brown’s girlfriend Karrauche, in a very awkward position considering that after the Grammy’s Chris Brown and Rihanna attended a party together, where everyone thought they looked like a couple.
