Pop starlet Mandy Moore is best known for her sweet song "Candy" — and a clean-cut image that defies scantily-clad junior vixens like Britney Spears and Christina Aguilera. Though aware she's less high-profile than they are, Moore is more concerned with staying true to herself.

As she tells TV Guide Online: "In this day and age, you're criticized for doing the whole sexy thing, but at the same time, you're getting so much attention for it that people end up loving it — or talking about it, at least — and I guess that's the whole point. It's a lot easier to go down that path, but it's just not me."

"I want to look back at photographs in 10 years and [think], 'Well, maybe that's not in fashion anymore, but at least I'm not embarrassed by what I'm wearing,'" says the 17-year-old. "I would be embarrassed if I was wearing some of that stuff [and I couldn't] pull it off. I have no confidence. I'd trip and I'd be hanging out of all my clothes."

Even if she's cautious in her dress, Moore's still willing to take chances. Co-starring with Once and Again's Shane West, the singer takes to the big screen in A Walk to Remember (opening Friday) — a transition that other musicians, like Glitter girl Mariah Carey, have failed to make before. "I'd love to continue to do other film projects," she says, "and if [this film's] a failure, then it's going to be a little bit of a hindrance. But at the same time, this was such a beautiful experience that no one can really take that away from me."
