Rapper Eminem denies he is dating a lookalike of his ex-wife Kim Mathers. The Without Me hitmaker sparked rumours he was dating music studio manager Marni Bright after they were spotted at FBT Studios in Ferndale, Michigan. But Eminem's representative, Dennis Dennehy, played down relationship reports. He tells New York gossip column PageSix, "They are not romantically involved." Eminem ended his one-year marriage to Mathers in 2006.
