Ashley Tisdale - I Want It All

"Ashley's my girl," says director Kenny Ortega. "She's just one in a million. I think Ashley is a classic in the making. I think she can deliver on many, many levels. She's just a fun spirit."

Kenny Ortega talked about the big production number called "I Want It All." "The song is Sharpay's version of how she sees the school in her fantasy world," says Ortega. "We’re all blinged out. We're colorful. Everything's totally different."

"It's the biggest musical number for me," says Tisdale. "Sharpay wants the Juilliard scholarship and she wants to use her brother to get it. The song itself is very Fergie/Gwen Stefani meets Sharpay Evans. I love it."
