He's grown up right before our very eyes!

Prince Jackson putt his buff arms on display in a cutoff workout t-shirt at Jiu Jitsu class in L.A. yesterday, and we almost can't believe that this is the same kid who late dad Michael dangled out a window in Paris all those years ago. Gone are the days off forced Mardi Gras masks, now he's all about the bandanas!

The 18-year-old is reportedly a straight A student with lots of extracurriculars, so there's no reason he shouldn't have his pick of colleges! According to In Touch, the King of Pop's eldest son is choosing between studying film at Loyola Marymount or USC, and began studying filmmaking with a college professor shortly before Michael's untimely death in 2009.

Sounds like he has set his sights on being the Prince of the movie biz!
