Kate Upton talked to the new issue of Details magazine about her meteoric modeling career, and said so far, its going pretty much just like she planned it. "Now it's out of my hands—it has kind of been rolling on its own—but at the beginning I was micromanaging every little step," Upton said. "For example, I felt that my agency before wasn't helping me in the direction I wanted to go, so I approached IMG myself. I always had in my mind where I should be at a certain stage." One thing the 21-year-old hasn't done yet, however, is a big-time fashion ad campaign. "Well, you'd be surprised how many offers I actually do get in fashion campaigns, but I unfortunately have to say no because my career is moving at such a rapid pace," she said. " Iwant to hit all the top things. I want Italian Vogue with Steven Meisel, but I can't do all of the other things because I also want to shoot a movie. You think you can do it all. I'm traveling everywhere and I'm trying to do everything and I can't. But I feel like the fashion world has welcomed me and nobody is scared of me." Another thing she hasn't done yet, either, is pose nude for a top photographer like top models Kate Moss and Naomi Campbell. "For me those photos are art. Your body is art, your body is beautiful, and to be photographed in that way is amazing and it's received in a very positive way. But with social media and the Internet and not so great blogs and the attention like that, I don't think that my pictures would be received in the way that I'd want them to be received," she said. "That's why I've stayed away from them. I really appreciate those photos and I think those women are beautiful, but I think social media and the Internet has prevented me from putting myself out there like that."
