Happy 17th Birthday, Miley Cyrus! When this megastar blows out the candles on her cake today, will she wish for:

A Porsche? Nah, got that already.

A kiss from Nick Jonas? Been there.

A spot on Disney Channel's 'New Year's Eve Star Showdown' lineup? Ding, ding, ding!

Beginning this Friday, Nov. 27, the Disney stars will duke it out for a spot on the Disney Channel's Dec. 31 evening lineup, the Hollywood Reporter confirms. Fans will be able to vote for their fave episodes and music videos at DisneyChannel.com. The winning shows will run on New Year's Eve from 6PM to 12:30AM, while songs from the 10 favorite music videos will play on Radio Disney, starting at 12PM on Jan. 1.

This fall, The Disney Channel will reel in viewers with the premiere of its first animated series in three years, 'Fish Hooks.'

The Hollywood Reporter details a 21-episode Disney order for the new 'toon show, which chronicles the underwater happenings at Freshwater High, a school submerged in a fish tank of a local pet shop.

Cartoon-rendered teen fish such as Piranica, Clamantha and Jocktopus deal with typical adolescent dating, homework and popularity issues, as well as seaworthy topics such as aquarium field trips to the pet store's hamster cagesand even an occasional assault from a giant lobster.

The last time The Disney Channel rolled out a new animated show was 'Phineas and Ferb' in 2007. President of entertainment at Disney Channels Worldwide Gary Marsh calls the 'Fish Hooks' effort "one of the most original, inventive animated series on television, bringing an ingenious twist to the classic archetypes of high school life."

The Jonas Brothers ... Jamie-Lynn Spears ... Miley Cyrus ... find out where they rank on our list.

Once upon a time, it was possible for a TV child star to get by on an impish smile and cute catchphrase.

Today's crop of kiddie performers don't have it so easy; they need to be double or triple threats who not only head up their own shows and/or TV movies, but sing, dance, star on the big screen, sell out concerts and launch clothing lines (despite some occasional personal missteps).

Here we count down the 20 hottest faves of the teen and tween pack.
