When Chris Hemsworth was named People's Sexiest Man Alive [1] last year, he joked that being sexy involves "squinting at the essential time" — and although he was kidding, there may be something to his theory. Over the years, handsome stars like Chris Pratt, Idris Elba, and Brad Pitt [2] have flashed squinty looks on the red carpet, and we can't help but notice that the sexy squint is definitely a thing. Sure, in some cases they narrowed their eyes because of sunlight or the flash of the cameras, but other times, it looks like they may have just been posing. Take a look at these pictures of some of Hollywood's hot guys to investigate: are they even hotter when they squint?
