Jay-Z plans to get fat.

The 40-year-old rapper - who 'retired' from music in 2003 to take up the position of CEO of Def Jam records before making a comeback -already has a "Marlon Brando retirement plan" in mind for himself and wife Beyonce Knowles in the future.

Explaining he wants to live on a private island, employ a "genius chef", smoke cigars, drink fine wines and get fat, the '99 Problems' star said: "That's what I enjoy. That's the payback for all the hard work.

"Beyonce will be on the island too. But I don't think she plan to get as fat as me. I'm gonna be fat."

The music mogul - real name Shawn Carter - also revealed one of the high points of his career was when U2 frontman Bono invited him and Beyonce to holiday at the 'One' hitmaker's home in St. Tropez, France.

Jay-Z added to Q magazine: "That's an invite everyone cherishes. Bono is an ambassador for the game. He's not, 'I'm Bono. F**k off'. He's still a musician trying to make the ultimate album."
