During a show on April 30 in Aspen, Colo., a fan who was tossing money around in the crowd was pulled on stage by Pitbull. The guy then thought it would be a good idea to make it rain in Pit’s face … and was dead wrong.

Pitbull suddenly levels the guy — repeat, LEVELS the guy — with a devastating right hand, then follows it up with a Beckham-esque kick once the dude was on the ground.

We’re told the fan was tossed out of the venue after getting socked — but was let back in once he convinced security he meant no harm. Cops were never even called to the scene.
