Valentine's Day is just around the corner, and that means love is in the air. But not all of us have a special someone to snuggle up with on the holiday. Instead of searching for the perfect Valentine's Day card for our sweetheart, we'll be at home watching episodes of "Girls" -- and fantasizing about our celebrity crush. Fortunately, we're not the only ones harboring deep desires for Ryan Gosling or Channing Tatum. Bing to see the sexy and sometimes surprising crushes of Kristen Stewart, Justin Bieber, Ben Affleck and more!
