Halloween is a holiday that brings out the big kid in all of us, and country stars are no different. A number of country stars dressed up and headed out for some costumed fun to celebrate Halloween 2016 on Monday night (Oct. 31).

Jason Aldean would have been unrecognizable in his excellent getup as the Joker, if not for the fact that the picture above was posted to his Instagram account, wishing his fans a Happy Halloween with his wife, Brittany, by his side.

Brad Paisley's wife dressed as Dorothy from The Wizard of Oz, while he went with the look she jokingly calls the "Tin Man upgraded" in this post to Instagram -- complete with a little dog who seems at least a little bit concerned about Paisley's unusual garb.

Kacey Musgraves is another star who really got into the spirit of the holiday. Even her biggest fans could have walked right past her in her costume and not known who she was.

Scotty McCreery and his longtime girlfriend, Gabi, were adorable in a clever twist on Charlie Brown and Snoopy.

Kelsea Ballerini got her dog, Dibs, in on the act, dressing him up like a cute little cowboy.

Brett Eldredge did a little early promo for his Christmas album, Glow, by dressing up as a dashing Santa Claus for Halloween.

And finally, Kelly Clarkson and her hubby got into the Halloween spirit by dressing as one of the Huntsmen and Buddy the Elf.
