We're still waiting on High School Musical 4 — and never giving up hope! — but in the meantime, we all have a chance at attending a cast reunion!

HSM star Monique Coleman is hosting a "private homecoming bash" with most of her onscreen classmates, including Ashley Tisdale, Vanessa Hudgens, Corbin Bleu, Lucas Grabeel, Kaycee Stroh, and Olesya Rulin — and you could be invited!

All you have to do is donate at least $3 to GimmeMo', the nonprofit Monique founded in 2010 to "address the most pressing issues facing youth globally."

The lucky winner (drawn at random from the list of donors) will be flown to Los Angeles for the soirée… and if you win, you can even invite a friend as your plus-one.

Sadly, Zac Efron won't be there to celebrate, but Monique says that he has a "special surprise" lined up for the winner.

Plus, if you donate at levels higher than $3, you get some sweet swag, including commemorative T-shirts and hoodies and autographed cast portraits.

The prospect of fangirling in the presence of our fave Wildcats is exciting enough, but it also feels great to know that we're empowering youth worldwide — "We're All In This Together," right?
