"We’re really excited to do this because this is actually our first duet together,” Ashley said. “We did not have a song in High School Musical, just the two of us. We always wanted one.”

Ashley's husband of two years accompanied the two women, and also did the arrangement for the video — check out the video below!

Our Disney fan-girling hearts are just about ready to explode! Not only have Ashley and Vanessa stayed best friends for over a decade, but Vanessa also served as a bridesmaid in Ashley's wedding to Christopher.
