If you happen to see Lady Antebellum and think they added a new member to their group, don't worry -- it's probably just Dave Haywood with a really big beard.

The trio recently signed on to participate in the the third annual No Shave November event, which benefits St. Jude Children's Research Hospital, and Haywood is their leading guy.

Team Lady A have pledged to let it all grow throughout the month, all in the name of charity. Haywood says, "After visiting St. Jude Children's Research Hospital and working with them for so many years, the place never ceases to amaze me. The love and support they provide for kids, as well as the life-changing treatment and research makes it a place completely worthy of all the support we can possible give!"

So, how does it work? According to the No Shave November signup page, a $30 donation and clean-shaven individuals can register to enter the challenge, beginning with a date-stamped "before" picture and ending with a hairy "after" shot. The Beard Bash will take place in Nashville, where prizes are awarded and a No Shave November Champion is crowned. After that, there may be a mad rush to the store for shaving cream.

Haywood is usually sporting a little bit of scruff, but fans should know that he won't be shaving it all off for the fundraiser. "Unfortunately, if I completely shave my face, I may look 15 years old again, but I will trim my beard low and not touch it for all of November!" he jokes. "So my version will be known as 'No Trim November.'"

Along with the trio, there are many other teams, including radio stations, companies and artists vying to see who can get the most participants and biggest donations for the hospital. Other participants include last year's top fundraising artist Keifer Thompson and Thompson Square (Keifer is this year's Honorary Chairman of the Beard), Benton Blount (who had a great chin-warmer last year) , Craig Campbell, Randy Houser, Dylan ScottAustin Webb, Big Machine Label Group and many others.

In its first two years, No Shave November raised more than $175,000 for the kids of St. Jude Children's Research Hospital. Here's to another spectacularly scruffy year!
