Oscar nominee Mickey Rourke has signed to wrestle WWE Superstar and lead singer of the heavy metal band 'FOZZY' Chris Jericho, at Wrestlemania 25 in Reliant Stadium on April 5.

Rourke, who played a professional wrestler Randy the Ram in his movie 'The Wrestler', announced Sunday before the SAG awards, is now challenging WWE Champion Chris Jericho for a fight, for real.

He said, I think I'm gonna do WrestleMania in Houston, and Chris Jericho, you better get in shape because I'm coming after your ass.

Meanwhile, Jericho, who made an appearance with Rourke on CNN's Larry King Live Monday night, said I think Mickey kinda talked a little out of line…there's a lot of a difference in playing a wrestler in a movie and actually being one in real life. He made a mistake and he was offended on Rourke's comment, and if you get your wish Mr. Rourke you will learn things you never learned in playing a wrestler in a movie.
