The battle of the teen stars has begun! We've picked the leading teen stars -- 20 of them to be exact -- in pop music for the ultimate fan vote face off. Miley Cyrus, Harry Styles (and four of his other One Direction bandmates), Demi Lovato, Justin Bieber and Cher Lloyd are just some of the names that made the cut for our Best Teen Star readers poll, and now it's up to your votes to see who takes the ultimate title.

Also coming in our Best Teen Star poll are Selena Gomez, Cody Simpson, Greyson Chance, Nick Jonas, Willow Smith and 'X Factor' youngins Astro and Rachel Crow. We mentioned before that we included Harry Styles of One Direction on our list as well, and his fellow 1D members that are under the age of 20 -- Zayn Malik, Niall Horan and Liam Payne -- have also made the cut.

Who else is the running for the Best Teen Star? Nickelodeon starlets/singers Miranda Cosgrove, Victoria Justice and Ariana Grande are also up for the title. And last not certainly not least, Bella Thorne and Zendaya of Disney's 'Shake It Up!' are included in our poll of teenage superstars.
