Ashley Tisdale, who stared as Sharpay in Disney's High School Musical, has a YouTube channel.
On her channel, Tisdale has a feature called "Music Sessions," and this week we were excited to see fellow High School Musical alumni, Lucas Grabeel or "Ryan". Watch below as they sing "What I've Been Looking For" from the movie. We love this mini-reunion!!
Check out their original performance below! They've changed so much!!
