Models, actors, and musicians are sometimes perceived as unintelligent because of the characters they play or the stigma of their careers– but there are a number of celebs out there who surprise us with their smarts.

From valedictorians to Ivy Leaguers to MENSA members, these celebrities are certified geniuses in their own rights.

But the former 'Punk'd' host lost his scholarships when he broke into his high school as a prank. He ended up at the University of Iowa, but dropped out at age 19 to pursue modelling.

'The sexiest thing in the entire world is being really smart,' Kutcher said at this year's Teen Choice Awards.
