Jason Aldean has a dirty little Christmas secret. His band and crew play 'Dirty Santa' every December, exchanging gag gifts that sometimes get a little racy.

"We had a road manager that was famous for wearing bikini underwear," Aldean tells Dial-Global. "So for Christmas one year, one of my guitar players bought him a couple pairs of G-strings. So then he decided to go put those on and come running out of the back lounge and model them for us. I threw up out the window!"

Aldean is home for the holidays with his wife and two daughters. He hits the road again January 16, kicking off a packed 2009 tour schedule in St. Charles, IL.
