Celebdom is so unfair. We get used to entertainers -- we crush on them, obsess over them, and follow their every move in tabloids (or in real life, if you're stalkery).  We actually invest in those actors, musicians, and singers! But Hollywood is fickle. Seemingly overnight, the world's hottest stars can topple from their place on the top of the fame food chain, never to be seen or heard from again. And we're left bereft, and confused, and wondering which curly-haired, pouty-mouthed blonde we can worship now that Ryan Phillippe can't get hired anymore. Oh, was that just us?

The late nineties and early aughts produced a slew of famous-for-a-second movie stars and platinum-selling singers who are rarely heard from today. From Mya to Neve Campbell, let's look back at our favorite stars who were famous for a red hot second.

Whatever happened to Mandy Moore, anyway? Check out our interview clip with the singer/actress from 2007.
