Ashley Tisdale and Lucas Grabeel reunited to perform their High School Musical duet.
During her YouTube music session this week, the Disney Channel alum welcomed a very special guest from her past.
The pair played iconic brother and sister Ryan and Sharpay Evans in the hit movie series.
In the first film, the pair sing two duets, Bop to the Top and What I’ve Been Looking For.
In this video, Ashley and Lucas sing What I’ve Been Looking For, in a stripped down version.
