13. Pink--Sick of being labeled "just another teen act" (even at the age of 21) after her release of "There U Go," she recorded "Mizunderstood" with the unbelievably hooky "Get This Party Started."

17. Joss Stone--Dubbed "the next Aretha Franklin" by some idiot, Stone is nevertheless an amazingly accomplished soul singer for being only 16 years old. Big with the adult contemporary crowd, her sultry cover of the White Stripes' "Fell in Love with a Boy" is wicked hot.

22. Shakira--Born in Barranquilla, Colombia, Shakira became an American sensation at age 23, capitalizing on the Latino pop trend set by Marc Anthony, Ricky Martin and Jennifer Lopez.

23. Hilary Duff--A classic "multi-platform" performer, Hilary first made it big as Lizzie Maguire on the Disney channel (which, by the way, is the birthing canal of most new pop princesses), moving easily into movies and now, recording. Her debut album "Metamorphosis" went triple platinum in 2003, at age 16.

24. Ashlee Simpson--Starting out as a cast member on TV's 7th Heaven, this 19-year-old sister of Jessica Simpson scored her own MTV reality show as well, The Ashlee Simpson Show, which documented the making of her first album.

25. Lindsay Lohan--Born in '86, a cast member of the soap Another World in '97, a starring role in the remake of The Parent Trap in '98, another hit with Freaky Friday in '03, Mean Girls in '04, and her single from Confessions of a Teenage Drama Queen called "That Girl" has just been released. She's only 18, which means you need to get to work.

26. Haylie Duff--The older sister of Hilary Duff by two years. Seen in Napoleon Dynamite, Haylie is currently on tour with Hilary, and co-starred with her in a really weird homo-riffic video remake of The Go-Go's "Our Lips are Sealed." Currently in a battle with Paris Hilton over the single "Screwed," which they both recorded. Oops.

27. Paris Hilton--According to MTV news, "The hotel heiress has been working on recording a dance pop album, which her producer Romeo Antonio describes as a cross between Jessica Simpson and Beyoncé." No label has picked it up yet. At age 23, she'd better hurry.

28. JoJo--Her appearance on America's Most Talented Kids got the attention of former Aaliyah producer Vincent Herbert, and she currently has a top R&B hit with "Leave (Get Out)." By the way, she's only 13. Oh, for the love of Christ.

29. Maria Mena--This 18-year-old Norwegian had some MTV airplay this past summer with the awkwardly cute, but mostly annoying song, "You're the Only One."
