Sources close to the top-selling rapper in history say his Sept. 17 concert in Dublin, Ireland, will be his last.
Mathers' right-hand man, Proof, told the Free Press Eminem " ... feels like he's accomplished everything he can accomplish in rap. He wants to kick back and get into the producing thing."
Detroit producer and Mathers collaborator Jeff Bass concurred, saying "the Eminem part of his career isn't going to be at the forefront anymore."
Mathers, 33, is not giving interviews and his rep at Interscope Records had no comment.
His manager, Paul Rosenberg, said Mathers' latest multiplatinum album, "Encore," is "certainly the cap on this part of his career."
Many speculate Mathers will follow his mentor, Dr. Dre, who left the spotlight to forge a career as producer and star-marker, the Free Press said.
