Here's Mike Tyson absolutely MASHING tennis balls during a lesson with his 7-year-old daughter -- who, by the way, is a frickin' PRODIGY!!!
Mike and Milan grabbed their rackets and went all smashy smashy -- Mike's form may not be the best, but you can see the insane power in his forehand and backhand swing.
But check out Milan -- who says her idol is Serena Williams -- and she's already winning youth tourneys with her impressive play!
... and if the tennis thing doesn't work out -- she's also got potential as a boxer!
