Paul McCartney is lending a helping hand to Kanye West for the latter's upcoming album.

McCartney is reportedly collaborating with West on a track entitled "Piss On Your Grave."

The story leaked in news papers however, representatives for West and McCartney have not confirmed the collaboration.
Another anonymous source responded to the reports,

"(West) has been tapping Macca up for a while about working together. Kanye and Paul have known each other for a long time but have become more friendly recently. There's every chance they'll head into the studio together."

Last October, McCartney revealed that albums by Jay Z and West were two of his most recent purchases.
