Good golly, Howie Mandel…
We know he's been working on his fitness…
But DAYUM, Mr. Mandel looks great for 58!
The America's Got Talent judge decided to take it all off on Monday night's show — joining an auditioning male dance review on stage!
Although he didn't quite stack up against the sexy beef cakes, Mel B and Heidi Klum still rushed the stage screaming at his striptease.
Howard Stern and Nick Cannon stood back in awe as it all went down!
Ch-ch-check out the Rock Hard Revue and Howie's moves in the video (above)!
