Eminem is considering putting an end to his public career in September, the Daily Star claims today.

The rap star apparently wants to retire after his world tour ends in Dublin in the autumn.

"Em has definitely gotten to the level where he feels like he's accomplished everything he can accomplish in rap," his D-12 bandmate Proof told the newspaper.

"He wants to kick back and get into the producing thing. Why not bow out when you're on top?"

Jeff Bass, co-writer of Lose Yourself, explained, "The Eminem part of his career isn't going to be at the forefront any more. As much as he caters to his fans, this has always been about putting food on the table. And he knows the right thing to do to make sure that happens.

"If that’s moving into producing 50 Cent and the other artists he's handling, then that's what it is. He's a smart guy. He knows what he's doing."

A friend added, "He feels like he's said everything he can say as Eminem. The idea that he intended this to be his last record is something that everyone on the inside circle has known for a while."
