Sir Paul McCartney is reportedly making music with Kanye West, as they head into the studio together.

The former Beatles singer and the outspoken rapper are said to have already recorded a number of tracks, that could be featured on a new album, reported New York Post's Page Six.

One song, tentatively titled P*** On My Grave, has already sparked some buzz, with Kanye's wife Kim Kardashian overheard telling friends she was a little surprised that the pair chose such a provocative name.

Kanye has spoken of his admiration for the Beatles in the past, while Paul has also said he would be interested in collaborating with a rapper such as Kanye or Jay Z.

The Beatles star even tweeted he had bought a copy of Yeezus and considered recruiting the Grammy-winning rapper for his song Appreciate.

Speculation over the rumoured pairing was sparked after Kanye was spotted in the crowds at Paul's gig at LA's Dodger Stadium last week.
