Today is Teen Wolf star, Dylan O'Brien's 21st Birthday!  He is my favorite character on the show, he plays Stiles Stilinski.  Seriously, he is the most adorable, funniest character! He is the main reason I watch the show.  And he's only 10 days younger than me, so I don't feel like such a creep ;)

In honor of his birthday, here is a little gallery of the cutie!
