Answer: The Next Big Thing in Girl Power.

Based on a 16-book series by Deborah Gregory, the Cheetah Girls have evolved through two feature films. The latest, aptly titled "The Cheetah Girls II", propelled the group to stardom, leading to an opportunity for a nation-wide tour.

The series of concerts, known as The Party's Just Begun Tour, has already started in earnest, drawing massive crowds at every venue thus far. Enthusiasm is slightly tempered by the absence of Raven Symone, former child star on "The Cosby Show".

However, other Disney notables are picking up the slack. Miley Cyrus, star of "Hannah Montana", is the opening act for several Cheetah Girls shows, while Vanessa Hudgens of "High School Musical" is scheduled to open for the Cheetah Girls during the latter part of the tour.

Some of the songs included in the setlist are "The Party's Just Begun", "Step Up", "Girl Power" and "Cheetah Sisters". The musical group is comprised of Adrienne Bailon, Kiely Williams and Sabrina Bryan.

Kid-friendly but hip enough for "tweens", the Cheetah Girls' success is built on a winning formula of catchy pop songs, energetic performances and uplifting values. There is no place for sex, drugs and mischief in the Cheetah Girls' message. Instead, it is a celebration of friendship, kindness and girl power. In their own immortal words, "It's Cheetah-licious!"
