21 Under 21 : Music's Hottest Minors (Part 2)

14. Miranda Cosgrove

Birthdate : May 14, 1993 (age 17)

Why She's Hot: Miranda Cosgrove learned a lot from the "School of Rock" … and by that, we mean the 2003 Jack Black comedy where she made her film debut. After breaking out on Nickelodeon's "Drake & Josh" in 2004 and starring in the network's hit comedy "iCarly," Miranda Cosgrove crashed the top 10 of the Billboard 200 with her debut album 'Sparks Fly," which peaked at No. 8 last spring. While more music is sure to come, Cosgrove is currently cashing in on her "iCarly" success -- Nickelodeon reportedly gave the starlet a seven-figure deal last March.

13. Chris Colfer

Birthdate : May 27, 1990 (age 20)

Why He's Hot: He portrays underdog diva Kurt Hummel on Fox's "Glee," but make no mistake -- Colvis, California's Chris Colfer is a bona fide champ in every way. Colfer's flaming falsetto helped inspire 12 million people to tune in to the season 2 premiere of "Glee" in September, and "Defying Gravity,'' his duet with Lea Michele (Rachel) remains the second most downloaded song from the show's catalog. With new Gleeks being born every day, we're confident Kurt's coming out party is just getting started.

12. Taylor Momsen

Birthdate : July 26, 1993 (age 17)

Why She's Hot: As the Twitter generation's resident bad girl, Taylor Momsen knows how to gin up a controversy or two. The "Gossip Girl" star steadily earned rock 'n' roll points this year by shunning the likes of Rihanna and Miley, and fronting her own band the Pretty Reckless, in which she strips down to racy lingerie in music videos and occasionally catches heat for adopting Courtney Love's grunge-goddess persona. Critics be damned, though, because between TV, music and her new gig as a spokesmodel for Material Girl, the clothing line helmed by Madonna's daughter Lourdes, Momsen's got her market cornered.

11. Lex Luger

Birthday: March 6, 1991 (age 19)

Why He's Hot: You may not know producer Lex Luger by name (yet), but if you've been blasting rapper Rick Ross' current album or Waka Flocka Flame's latest single, you're definitely familiar with his skills. The 19-year-old Virginia-born, Atlanta-raised studio whiz is responsible for chart bangers like Ross' "B.M.F." and "MC Hammer," and Waka's "Hard in the Paint," among others. He's also working with Fabolous and Kanye West on their upcoming albums, among other top-notch artists, and is set to become one of the most sought-after producers in the game over the next 12 months. Swizz Beatz better watch his back.

10. Miley Cyrus

Birthdate: November 23, 1992 (age 17)

Why She's Hot: She was cast as Hannah Montana at age 12, and when the show premiered to the Disney Channel's largest audience ever, Cyrus was an instant teen idol. The "Hannah Montana" franchise has spawned four seasons, a string of hit singles, a full-length movie and enough branded merchandise to fill up a middle school gymnasium. Cyrus' ascent toward adult famedom ramped up earlier this year, when she released a more mature-sounding album, "Can't Be Tamed" in June. The album didn't quite tame the charts though, and Miley appears to be focusing more on her acting career with three films ("LOL: Laughing Outloud," "Wake" and "Wings") in the works. Still, we don't expect the unflappable Miss Cyrus to stay away from the record studio for too long.

9. Greyson Chance

Birthdate: August 16, 1997 (age 13)

Why He's Hot: Anyone who can reinvent a hit by Lady Gaga deserves a close listen -- and when that person is just 12 years old, they deserve about 32 million close listens ... and counting. When now-teenage Oklahoma native Greyson Chance sang "Paparazzi" at his school talent show with the flair of someone who's been in the music game for years, he became a overnight viral phenom. A record deal quickly followed, and Chance now shares managers with none other than his idol, Gaga, and her own progenitor, Madonna. Look for Chance to make another big splash this fall, when he drops his rock-inspired debut album.

8. Demi Lovato

Birthdate: August 20, 1992 (age 18)

Why She's Hot: Demi Lovato, who got her start on TV as one of Barney's little friends, has used her roles in Disney Channel ventures like "Sonny with a Chance" and the "Camp Rock" franchise to forge a successful singing career. The 18-year-old Dallas native went all the way to no. 1 with her sophomore disc "Here We Go Again" in 2009. Lovato is currently working on her follow-up disc, touring with her "Camp Rock 2" co-stars the Jonas Brothers, and lighting up red carpets around the globe.
