High School Musical actresses Vanessa Hudgens and Ashley Tisdale have shared some funny cuts from their reunion on the Disney Singalong Special having aired on Thursday.

Vanessa, 31 shared an out-take on Twitter which shows her on her patio with her hands in the air and singing.

But she suddenly freezes and stops singing before coming back to the camera and confessing to the person filming that she “messed up”.

While she doesn’t reveal why she dropped a clanger it could be because she was put off by a loud aircraft which can be heard flying overheard when she started her routine.
