If you've noticed Joe Jonas sporting more facial hair lately, it's not because he's been lazy about shaving. The 22-year-old has been growing a moustache in support of Movember, a month-long campaign to raise funds and awareness for men's health.

Movember takes place each November. Guys start by shaving their faces clean and then grow and trim their facial hair until they can boast a healthy 'stache for the cause. Every guy involved acts as a walking billboard for the event, which specifically focuses on bringing awareness to prostate cancer and other cancers that affect men.

Joe's not alone in the Movember movement -- Justin Bieber, Foster the People's Mark Foster and more have been vocal about supporting the important cause.

For more information about Movember, check out its official website and take a look at more sweet celebrity 'staches that have been grown for the campaign on AOL Music.
