Kanye West has blown rap mogul Jay-Z's big comeback surprise by announcing he's on board to produce the Def Jam Records boss' next project.
Jay-Z announced his retirement in 2003, and has been dogged by rumours of a comeback ever since.
He has always maintained he has no plans to return to the charts, but now West, who produced his The Blueprint album, reveals the rap boss is staging a comeback in an interview in the new issue of men's magazine Playboy.
The Jesus Walks hitmaker says: "I'm producing Jay-Z's new album. I'm doing the whole thing."
And when interviewer Rob Tannenbaum reveals Jay-Z once offered to pay him $1,000 (€836) if he ever came out of retirement, West tells the journalist: "Well, he's about to pay."
