It's been over a decade since the first High School Musical movie debuted on the Disney channel, and in the time since, the cast has spiralled off into wildly different directions. But if we learned anything during our time with the crew, it's that once you're a Wildcat, you're always a Wildcat. Coming off the epic 10-year reunion in 2016, the latest mini get-together featured the two biggest starlets from the series, Ashley Tisdale and Vanessa Hudgens. Tisdale welcomed her former costar to her YouTube channel to sing a sweet cover of "Ex's & Oh's." Considering how the two never had a duet in the HSM movies, it's like we're getting the pairing we never knew we needed . . . until now.
