High School Musical is one of Disney’s most successful productions to date, it is loved by millions across the globe and now the stars of the series reunite once more, but this time for charity.

Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Lucas Grabeel, Kaycee Stroh, Olesya Rulin and High School Musical director Kenny Ortega will come together  in December to raise money for co-star Monique Coleman’s non-profit foundation called GimmeMo’ which was designed to help create programs to improve the lives of youths all over the world.

The reunion is being held to commemorate the five-year anniversary of High School Musical 3: Senior Year in October 2008.

Unfortunately for many fans of the musical, leading man Zac Efron will not be in attendance, but is expected to record a special message for the occasion.
