Ashley Tisdale and Vanessa Hudgens sing first ever duet together

Best friends Ashley Tisdale and Vanessa Hudgens have sung their first ever duet together.

In a video posted to Tisdale’s YouTube channel yesterday, the pair sung an acoustic version of Elle King’s ‘Ex’s & Oh’s’.

Before singing, the duo revealed they didn’t have a chance to sing together while filming the ‘High School Musical’ films.

“We were really excited to do this because this is actually our first duet together,” Tisdale said in the video.

“We did not have a song in ‘High School Musical’.”

The former co-stars have remained close friends since the film franchise ended.

They have featured heavily on each other’s social media pages, and Hudgens was a bridesmaid at Tisdale’s wedding to composer Christopher French.
