Rumor has it that Paul McCartney is secretly recording music with none other than Kanye West.

According to the New York Post's gossip column Page Six, the two have a number of songs that they've written and rehearsed together, and there's even the possibility of a full album, sources claim.

The idea of a collaboration isn't new for McCartney, who has previously said that he'd like to work with a high-profile rapper like Kanye or Jay-Z.

Early buzz about a single titled "Piss On Your Grave" has begun, a title that the Huffington Post confirmed with reps for Kanye on Monday after it was reported that the single was titled "Piss On My Grave."

Further evidence of a collabo happened just over a week ago, when the former Beatle played at Dodger Stadium in Los Angeles. Kanye was reportedly at the concert.
