Has Kirsten Dunst revealed too much? At 18, her shapely form has clearly filled out in all the right places. But now, the actress confesses that she's had second thoughts about serving up the evidence with provocative photo spreads in mags like Details and Maxim — not to mention the daring duds she donned at the MTV Movie Awards.

"It's weird," she says, "because I'm at this place where I'm very comfortable with my own body, but I have this role model thing. I know that some kids do look up to me. Recently, I've been wondering, 'Have I been too sexy?' I think sometimes it's sexier not to show too much, and I think that's where I'm headed now.

"I'm not into showing everything in a magazine anymore," Dunst sums up. "It's like, 'What's the point?' It's not that interesting to reveal all of yourself."

While she's still willing to employ her sexuality when necessary for her art, Dunst reportedly nixed a prolonged nude scene in crazy/beautiful (opening tomorrow). And interestingly, her portrayal of a drug-addicted, suicidal misfit puts her back on the dark side she explored in The Virgin Suicides. "I loved the role," Dunst shrugs, "because I felt I could show people that I'm more than the sweet, cute little cheerleader girl I played in Bring It On. I don't want to get stuck in that 'She only plays the cute girl' category. That's why I didn't care how I looked. I let them chop off my hair and I said, 'Just make me look bad.'

How will Dunst look in the much anticipated Spider-Man? "I get to wear a red wig," she reveals, "and I get to do a lot of action stuff. I spent almost every day on the set in some sort of harness for a stunt scene. It was great."
