Rihanna is set to release a single featuring her former lover (and batterer) Chris Brown, according to a Life & Style report.

It will be a full version of an interlude titled "Birthday Cake" from her lasted album Talk That Talk, according to the report.

"Chris and Rihanna are friends again," his rep told the mag. The two have been spotted out at the same nightclubs and parties recently but both deny they've rekindled their romance.

Three years ago, Chris attacked Rihanna after a Grammy party and in June 2009, Brown pleaded guilty to a felony assault charge; a restraining order was issued. In February 2011, the order was downgraded, which allowed the singer to have contact with his former girlfriend.
