Justin Timberlake does not want to marry Cameron Diaz.

Justin Timberlake has been dating Cameron Diaz for three years now, but all he seems to be talking about is how much he DOESN’T want to marry her.

Ellen DeGeneres asked him about buying a bridesmaid dress for his wedding while he was a guest on her show and he told her that she will have to "stay the same size for the next 15 years" if she purchased one now.

Justin followed that up by telling Jay Leno that the pair "like having sex..Why would we want to ruin a good thing and get married?"

Ouch. Hopefully Cameron has no aspirations to be Mrs. Timberlake or Justin is going to get himself into some trouble. Maybe instead of bringing sexy back, he should be bringing silence back. He’s not going to be getting sex much longer if he doesn’t learn to be quiet about how much he doesn’t want to marry his gal.
