A demo of a supposed new Rihanna collaboration with Beyonce has appeared online.

7 Keys, mooted to appear on Rihanna’s anticipated upcoming album R8 (working-title only) surfaced on the web late last night, around the time RiRi dropped her new Kanye West & Paul McCartney-featuring single FourFiveSeconds, however the demo, if indeed legitimate, seems to have a huge amount of vocal distortion embedded across – subsequently it’s tough to make out whether it is indeed Rihanna and Beyonce on the cut. We’re not convinced, put it this way…. but hey, with all the R8 rumours circling, we thought we’d bring you all the juicy gossip we could find!

Make up your own minds on 7 Keys below; in the meantime, FourFiveSeconds is out now and can be downloaded via the iTunes link:
