Kate Upton doesn't think she ''can do it all.''

The 22-year-old model, who is dating baseball player Justin Verlander, is still very ambitious, but claims she struggles to find time in her busy schedule to do everything she wants to do.

The 'Other Woman' actress told Details magazine: ''My career is moving at such a rapid pace. I want 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 travelling 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.''

The Sports Illustrated beauty would also love to pose naked for a tasteful photoshoot, but thinks she would attract a lot of criticism for it.

She said: ''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 added: ''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.''
