Well folks, you were right. It really was Stapleton.
As it turns out, the country music star is a fan of the show and landed a guest spot, along with his bassist J.T. Cure and his tour manager.
Stapleton took to Instagram following the episode to share a behind the scenes picture from the Ireland set and fans immediately went wild.
Although the moment was fleeting and just a close up of his eyes opening — Stapleton said it was worth it.
