Photo: Drake and Chris Brown in the studio together

Two years ago, Drake and Chris Brown's rivalry over Rihanna came to a head with a fight at a night club in New York. Fast forward to now and they are in the studio together.
A friend of Chris who tweeted the pic said the former rivals are making music together.
After the pic, which was taken last night, was released online, Team Breezy, The Rihanna Navy and whatever Drake's fan call themselves went into meltdown. Should Rihanna be concerned?
