Chris Brown & Drake — Photo Proof the Rihanna Beef Is Squashed

Mortal enemies Chris Brown and Drakeproved their long-standing .. and sometimes violent Rihanna beef may finally be over for good — and they might be sealing the truce with new music.Drake posted a pic last night of himself and Chris in a recording studio — and Breezy looks like he’s LOVING whatever music they’re listening to at the moment.There were rumors the feud was over, but this is the first visual evidence. Pretty amazing … considering the beef exploded 2 years ago in a massive brawl at W.I.P. nightclub in NYC. Chris and a bodyguard were left bloodied, and NBA star Tony Parker suffered a serious eye injury.Peace has been brewing since last April when we spotted Chris in a club dancing to a Drake hit.They’ve come a really long way.
