We’re not sure what’s going on with Chris Brown these days, especially with his on and off again girlfriend, Karrueche Tran.

But at least Chris has finally put his differences aside with former enemy, Drake.

Both Chris and Drake are seen hard at work in an Instagram picture taken by rapper, Elliot Wilson. The snap shows Chris singing, while Drake listens approvingly. Both Chris and Drake have dated Rihanna at one point.

The picture is made even more surprising, considering the infamous bust up the two stars had over Rihanna in a New York nightclub back in 2012. But that all seems to be in the past, as the stars have put their differences aside for their latest track.

But what we want to know is what brought the two stars together in the first place, and most importantly what would Rihanna think of this?
