He's reported to have signed a £2m deal with a company in America, who also sell clothes designed by rapper Jay-Z.
A spokesman for the company told the Sun newspaper that "the clothes will be a pure reflection of Eminem and what he'd be wearing."

At CBBC Newsround we reckon the sizes of clothes could be interesting, perhaps coming in large, medium and slim!
