Taylor Swift is making a career out of singing sweet country-pop love songs. On her latest album, Fearless, she worked with "Bubbly" singer Colbie Caillat, and she told MTV News she would even like to work with the subject of her first hit — Tim McGraw — someday. But, Swift said there's a more tantalizing duet she's hoping to make happen.

"I'd like to do a completely off-the-wall collaboration," she said. "I would like one of my songs to be the hook to a rap song. That would be so much fun! You know, I love Kanye West and I love T.I. — he's amazing."

If Swift's love of hip-hop wasn't surprising enough, she also has a shady side — the bouncy teen star told us that the only way you'd get her to leave music for acting is if she could embrace her inner bad girl and play a criminal mastermind.

"I think, as far as branching out with acting, it would take something really right on the mark to distract me from music, because music is everything to me," she said. "If it were 'CSI' or 'Grey's Anatomy' or a movie that was really, really smart, then I think I might venture off.

"I could be a crook," she said of a possible cameo on the crime drama "CSI." "Hopefully one that's really twisted, that took, like, four episodes to figure out." But it wouldn't take much of a story line to get her on "Grey's Anatomy."

"On 'Grey's Anatomy' I wouldn't care what I was playing — I would play a corpse, 'cause I love it that much. It is deep true love and it will never die."

It pretty obvious that the VMA-nominated country chanteuse is always ready to try something new — she's goal-oriented, but vows to not define herself by her ambitions. "As soon as I accomplish one goal, I replace it with another one," she explained. "I try not to get too far ahead of myself. I just say to myself, 'All right, well, I'd like to headline a tour,' and then when I get there, we'll see what my next goal is."

In fact, her pop career replaced her previous ambition of going to college, where she probably would have studied video editing. And although she's the right age, Swift said she just doesn't see it in the stars for her at this point. "College, to me ... I always thought I was going to go. Both my parents went to college ... so I thought that's what I was going to do, but life took a different turn," she said. "And I think that college is great because it can be a wonderful tool to make you well-rounded and get all these social-networking skills."

Swift is learning those things on the road and in the recording studio — it's the type of education she feels is better for her at this point in her life. "The things you learn in the classroom are one thing, but ... part of me thinks that being on the road, the promotion of an album and management ... learning all of those things, I think, makes you well-rounded, too."
