This High School Musical Reunion Will Make Your Heart Sing

It's been 10 years since High School Musical first captured our hearts. In celebration of the big milestone, the cast reunited for a Good Morning America interview on Tuesday and a special telecast of the movie, which will air on Wednesday. Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Luke Grabeel, and Monique Coleman all got together at a gym in suburban Los Angeles (but let's just pretend it's really the home of the Wildcats) to shoot their part of the special. Don't worry, Zac Efron will appear in a taped message. For now, take a look at the video from Good Morning America and Instagrams that the cast shared!
