Steve-O Calls Out Fat Eminem

LOS ANGELES (Wireless Flash) -- Steve-O is putting his money -- and a microphone -- where his mouth is.

'Jackass' star Steve-O now wants to 'save rap from ring tones' with a new album: 'The Dumbest A**hole in Hip Hop.'

On his debut rap album, "The Dumbest A**hole in Hip Hop," Steve-O -- best known for his ball-busting, scary stunts on MTV's "Jackass" -- is bringing rap back to its raunchy roots.

"I'm saving rap from ring tones. Rap is about drugs, guns, and naked chicks," Steve-O said. "I'm rapping about cleaning the cocaine off my credit card. If people don't like it, they can suck my d**k!"

Steve-O drops lewd lyrics on songs like "Down with STDs," "Crack Cocaine (Feels So Good)," and "Poke The Puss," but he insists he's got serious street cred and isn't afraid to fight.

He says, "I ain't new to being filthy rich like rap stars. Eminem lost his figure, but I'm looking better than ever, and I'd never pick on my mom or whine about a b*tch like he does. I'm the greatest white rapper on the West Coast. I'm the sh*t!"

"The Dumbest A**hole in Hip Hop" drops February 14.
