Just days after she celebrated boyfriend Matt Kemp's birthday in at Drai's in Hollywood, the R&B superstar was spotted sneaking in the back door to Drake's party at Green House in NYC!

Or maybe Rihanna is so over Drake it's just a comfortable friendship these days? They ARE working on a duet together...
