Actresses Vanessa Hudgens and Ashley Tisdale reunited with their fellow High School Musical co-stars on Friday (29Aug14) as part of a contest to support a youth charity.

It was a night to remember for superfan Camilla Simon, who won a raffle to spend an evening with her favourite Disney stars.

Hudgens and Tisdale were joined by Corbin Bleu, Monique Coleman, choreographer Chucky Klapow and director Kenny Ortega for a dinner in Los Angeles, and they all took to social media to share photos of their night together.

Tisdale shared a photo of herself along with Hudgens, Ortega, Coleman and Simon on, and added the caption, "Had so much fun seeing everyone and hanging with the Prizeo winner!", while Hudgens shared a similar picture and wrote, "Such a wonderful little Hsm reunion (last night). @Ashleytisdale and Ko (Kenny Ortega) laughing our a**es off."

Noticeably absent from the event was Hudgens' ex-boyfriend Zac Efron, who stated he couldn't attend the dinner because he is currently filming his next movie, We Are Your Friends.

Proceeds from the contest benefited Coleman's GimmeMo' Foundation, which addresses pressing issues facing youth around the world.
