Are any of the following celeb guys gay?

LEONARDO DICAPRIO ISN'T GAY!!!! He took the role in Total Eclipse to prove he seriousness as an actor and he's deversity! He's a fantastic actor and one of the best looking, but that's not why I like he so much! I will go see any of he's movies! He's one of the best (if the THE BEST) young (yes, he is still young, he's only 33) actors in Hollywood. He dates supermodels for goodness sake! Jay Leno isn't gay either, I just needed to let you know that, he's not. That would be strange. As for Ryan Seacrest and Zac Efron...I really don't know. But Leo and Jay aren't!
