Ten Most Powerful Girls in Hollywood

MILEY CYRUS: THE REAL-LIFE DISNEY PRINCESS, 15
Currently on a sold-out tour as her Disney darling alter-ego Hannah Montana, Cyrus does it all - singing, dancing, acting, and merchandise deals - with nothing but smiles. The superstar earned $3.5 million last year.

TAYLOR SWIFT: THE COUNTRY DARLING, 18
After Swift's self-titled debut album sold 2 million copies, her record label gave her a tricked-out pink 2008 Chevy Silverado as a birthday gift that the home-schooled high school senior donated to a children's camp.

RIHANNA: THE HITMAKER, 19
Her "Umbrella" was the song of the summer - spending seven weeks at the top of the charts - but the singer says she's not done yet: "I'm looking at getting into film, and I'm working on my own businesses." She's already hawking a line of umbrellas.

VANESSA HUDGENS: THE DREAM TEEN QUEEN, 19
Despite a nude photo scandal, the actress-singer made $2 million last year thanks to the Disney juggernaut High School Musical. "It's time for a new generation," she says. "To be a part of that is really cool."

ASHLEY TISDALE: THE HIGH SCHOOL HOTTIE, 22
HSM made her a star - and her new nose gave her plenty of attention - but what gets Tisdale most excited? "I have a Barbie doll coming out," she tells Us (not to be confused with her HSM doll).

THE CHEETAH GIRLS: THE TRIPLE THREAT: BRYAN, 23, WILLIAMS, 21, BAILON, 24
Sex may sell, but so does the made-for-Disney Channel girl group's messages of self-acceptance and female empowerment: their first CD sold more than 2 million copies and their tour raked in $26 million.

BLAKE LIVELY, THE GOSSIP QUEEN, 20
The Gossip Girl star says her school days helped prep for her role on the CW hit: "I was in all advanced placement classes, six clubs, cheerleading. And I was class president."

AMANDA BYNES: THE MULTITASKER, 21
Last year alone, Bynes starred in the blockbuster musical Hairspray, the romantic comedy Sydney White and launched her own clothing line, Dear. All that and she's twice been on Forbes' list of the 100 most powerful celebrities.

RAVEN SYMONE: THE MINI-MOGUL, 22
Dubbed the $400 Million Woman by Ebony for the estimated revenue her That's So Raven show has brought Disney, Symone just launched Ravensymonepresents.com.

ELLEN PAGE: THE QUIRKY BREAKOUT, 20
Starring in the indie hit Juno is just the beginning for this actress: she's been nominated for an Academy Award and a Golden Globe for her performance and costar Jennifer Garner dubbed her "the most powerful woman in Hollywood."
