Why wait for Throwback Thursday when you can have Way Back Wednesday with a mini High School Musical reunion?

HSM co-stars Ashley Tisdale and Vanessa Hudgens tag-teamed on a rendition of Elle King's "Ex's & Oh's" for Tisdale's YouTube channel, as requested by some eager fans who wanted the real-life best friends to reunite for a performance -- because they actually never got the chance to duet in all of their High School Musical years. Tisdale's husband, composer Chris French, chipped in, preparing the arrangement of the song and playing guitar for the girls while they harmonized in true BFF fashion.
