A song produced by Calvin Harris and featuring the dulcet tones of 'Gentleman' denier Tinashe has surfaced online.
It's called '5AM' and sounds an awful lot like this (via Ultimate Music):
There's specÂuÂlaÂtion this could have been the song Calvin was chatting about late last year that was intended for Rihanna but basically she wasn't feeling it.
It defÂinÂitely sounds like Rihanna could have done it.
