Nick Cannon, the husband of pop diva Mariah Carey, has launched a scathing attack on the “Touch My Body” singer’s former boyfriend, Detroit rapper Eminem. The controversial hip-hop star has made no qualms about poking fun at his former spouse… and now Cannon has had enough.

In a brand new track on his upcoming Relapse LP, titled “Bagpipes From Baghdad”, Eminem jokes that he wants to have another “crack” at the singer, who he dated back in 2001. “Nick Cannon better back... up / I’m not playing, I want her back, you punk,” he raps.

Cannon has responded to the song by saying he “felt sorry” for Eminem, blogging on his website that the MC must “really be stuck in the past”.

“Not only has his music not evolved, but also homeboy is still obsessed with my wife, the same female that wouldn’t let him get to second base from eight years ago,” Cannon wrote. “What type of grown...man lies about getting with a chick? Only Slim Lamey! LOL!”
