Get ready, because the Wildcats are back in the house! Well, almost. It's been officially announced that the High School Musical cast is coming together for a 5-year reunion. And the best part? It's all for charity!

In December, the cast is reuniting to support the GimmeMo' Foundation, Monique Coleman's nonprofit organization, which is dedicated to empowering today's youth all over the world. Their party will take place in Los Angeles, but one lucky winner and a friend are going to be flown out to attend, and all it takes is a simple donation.

So far Vanessa Hudgens, Ashley Tisdale, Corbin Bleu and Lucas Grabeel will be there, among other cast members. Unfortunately Zac Efron isn't going to be able to attend, but he's making sure to keep his head in the game by creating an extra special video for the winner!

Are you excited about the reunion? Let us know in the comments!
