When most people turn 21, they usually celebrate by over-drinking and making decisions that they either regret or can't remember.
Not Demi though! Obviously her partying days are done, but Demi thought that spreading the love ought to be involved in her big day in a big way, too.
Demi spent the day working with Free The Children, a charity and educational partner that empowers youth to be more active in their community, confirming this master of sass is also a master of class.
Demi might be Made in the USA, but she's into showing Africa her love! Look at her carry that wooden keg thing with her head. Gurl is headstrong in so many ways!
Happy birthday, Demi!!!
