The Smile singer posted a photograph from the shoot on her MySpace page, along with a caption inviting fans to guess the identity of the man in the picture.

She wrote: “Shooting a video for ‘Everyone’s at it’. Here’s a picture I took on my cellular telephone. We are having fun, can you guess who it is? (No it’s not me).”

The post caused fans to reply in their hundreds, with the majority deciding the man bears an uncanny likeness to Purple Rain singer Prince.
