It's totally normal to have celeb crushes...and even to be a little jealous of their paramores.
I've loved Joshua Jackson since I was 12 and saw the Mighty Ducks...and just my luck, he's with Diane Kruger - possibly one of the most beautiful women in the world.
Don't feel weird about Ty Burrell...I have a thing for Gary Oldman - pretty much since I saw Sid and Nancy as a teenager.
Bradly Cooper since he played the nerdy side kick on Alias
Captain America is one of the most boring movies I've ever sat through - but seeing Chris Evans shirtless made it well worthwhile.
John Schneider...I wanted to marry him when I was five. And then I realized I must be a grownup when watching Smallville I found papa Kent so much hotter than his son.
Finally...Christina Hendricks...If I was ever to go that route - she would be it. Absolutely gorgeous (and not a size 00)
It's fine as long as it is in good fun. I did have a friend who talked so much about Chris Evans that she was starting to annoy her husband and then it did get to the point where it was interferring with reality.
