It has recently been reported that Kanye West is secretly recording several tracks with Paul McCartney that can possibly be developed into a whole album.

According to The New York Post's Page Six, the Chicago emcee has teamed up with the former Beatle to create the follow-up to his 2013 sixth studio experimental album "Yeezus." One of the collaborative songs is apparently titled "Piss on My Grave," and wife Kim Kardashian has been heard telling her friends that she was a bit surprised at the musical duo's provocative decision.

West added fuel to the pair's collaboration rumors, as he and his representative, who both have declined to comment on the recent claims, were present at McCartney's show, which took place at the Dodger Stadium in Los Angeles on Aug. 10.

Moreover, the Sun reported that the "New Slaves" rapper and the classic rock legend have become good friends recently. "Kanye and Paul have known each other for a long time but have become more friendly recently," a source revealed. "There's every chance they'll head into the studio together."

The source added that the two artists already met up to discuss working on the new record, which they will keep it a secret. "Kanye really respects music legends and is still putting the finishing touches to his new album. He has been tapping Macca up for a while about working together," the source said. "They've had a few meetings with each other but both of them always keep their collaboration under wraps until the last minute."

In addition, Paul McCartney previously showed his interest in collaborating with Kanye West. While he went on an interview with Zane Lowe to promote his solo album "New," the 72-year-old rocker admitted that he had "resisted the temptation to get a rapper in" for his funk track "Appreciate."
