Tisdale didn't stop at riding around on Efron back through the ocean waves.

Kind of reminds us of the High School Musical plot, were Ashley Tisdale playing the part of Sharpay Evans the drama queen wants to be the center of attraction for the varsity basketball caption Troy Bolton played by Zac Eftron.

Perhaps the movies imitate real live or visa versa.

Ashley Tisdale also recently stared in the DVD release Sharpay's Fabulous Adventure which was based on Ashley Tisdale High School Musical character Sharpay Evans.

The film follows Evans after high school graduation in her quest for a role on Broadway.

Ashley Tisdale also played the part of a cheerleader captain in the television series Hellcats.
