Could this be the most unlikely couple ever?

There’s been rumours that Katy Perry and Robert Pattinson have been dating for some time now – but this is even crazier!

It has now been reported that Katy will be helping Robert on his début album as he attempts to launch a music career.

Robert attended Katy’s Prismatic tour in London last night also, could these two be seeing each other?

Hmm, we wonder what a duet between these two would sound like?!
