Chris Brown and Drake — WE’RE BOYS NOW … Squash Rihanna Beef On Camera

Chris Brown and Drake have BURIED THE HATCHET after the bitter, bloody, bottle-throwing Rihanna-fueled beef … and the reconciliation was all captured on video.

Brown posted a video on Facebook last night that was shot in a recording studio — and it shows a bunch of superstars who are collaborating with CB.

But the shocking part … one of the people in the studio is Drake — who is not only hanging out with his former arch-nemesis, but the two BRO OUT with an “I don”t hate your guts anymore” handshake.

Pretty crazy how far these two have come — since it was just last year when their entourages brawled in a NY nightclub, leaving several innocent bystanders with major injuries, including NBA star Tony Parker.

It”s unclear when or how the two settled their differences — but according to reports … they were seen hanging out at the iHeart Radio Music Festival in Vegas last month.

Maybe they bonded over this …
