Simon Cowell – 5 Feet 8 Inches Tall

Cantankerous talent show judge Simon Cowell is a Godzilla-sized nightmare to many singers, but in reality he's so height-challenged (and so insecure about it) that he reportedly wears lifts in his shoes and bristles at jokes doled out by friends like Victoria Beckham.

Being shorter than average hasn't hurt his prospects with the ladies, though, since it's amazing how much taller men look when they have enormous ... bank accounts.
