There's no denying that these 13 celebrities are insanely attractive — but that doesn't necessarily mean they're perfect. We've noticed that there's one thing they all have in common: a naturally lopsided smile. See what we mean, starting with… "Game of Thrones" star Natalie Dormer. "I get accused of having a haughty smugness," Natalie told The Sunday Times in 2014 while promoting her role in the "The Hunger Games: Mockingjay — Part 1." But it's not her fault. "I have a lopsided mouth. I can't help it — I was born with it," she added. "It looks as if I am smirking. I have had my publicist tell me, 'Don't do that smile on the red carpet.' I'm, like, 'That's my smile.'" Keep clicking for more stars with natural-born smirks …
