A new album, a movie debut and the cover of ym—what else can Mandy Moore possibly have time for? You'd be surprised.

Well, besides turning 17 on April 10, this awesome Aries is also gracing the cover of ym's May issue, where you can find out what happened when we dared Mandy to serve up fries at a fast food joint and hand out cotton candy to total strangers. You want Moore? You got it. Look for her new album-release in June — the single's called "In My Pocket" — and her first movie, The Princess Diaries, due out in April. And like this chick's not totally booked already, she's also heading back to MTV to host Mandy this spring.
