Ladies, you'll want to sit down for this. These days, Luke Bryan is known for shakin' his groove thang in concert -- in skin-tight jeans, no less -- but the star admits he won't pull the Beyonce moves at his shows forever.

Tragic, we know. At 38, Bryan is still young and full of energy, so he's ready to dance for his fans each night as he belts out country hit after hit, but that won't always be the case.

“Ten years from now will I be on stage dancing? No I won’t be," he tells 'Nightline.' "I would certainly say it will be much more tamed."

For now, fans can continue to enjoy Bryan busting a move onstage at his shows, and thankfully, he's out on his huge That's My Kind of Night Tour.

“I’m up there being really free, relaxed and chilled out ... and that’s really our basis for getting up there and dancing and having fun," he assures.

Bryan's fans have come to know and love his moves -- okay, and his butt -- so much that they've even created mashup videos of his shakin' and Twitter handles dedicated to his rear. While he may not understand all the hype, Bryan does find it flattering:

“And if fans want to create fan pages dedicated to my butt I will take that as flattering."
