Arrange beanbag chairs and comfortable seating around the television for the girls to relax, chat and watch the "Cheetah Girls: One World" movie. Some tweens will prefer to have the party with parents tucked silently in the next room, and a comfortable gathering place for girl talk will be inviting to party guests.
Decorate couches and chairs with colorful cheetah covers -- the more colors the better. Decorate the walls with Cheetah Girls posters and posters from the movie. These posters can be party favors for girls to decorate their own rooms at home.
Provide a makeup mirror for the girls with makeup. Allow the girls to take turns putting on makeup, with parental permission, and give them a karaoke machine or other video game system they can use to perform. Once they are all dolled up, they can take turns putting on a show to their favorite Cheetah Girls tunes.
