Adele is the world's favorite cussing, golden-piped singer, and she stayed true to form during a tour stop in Lisbon, where she mixed up the lyrics to her own song "Million Years Ago" and then reacted appropriately.

Adele started singing a verse rather than the chorus, and even though fans might not have noticed if she just had just gone along with it, Adele pointed out her flub immediately.

"Shit, wrong words! Shit. Shit. Shit," she laughed. "Sorry!"

The 25 singer, who reportedly just signed "the most expensive deal in music history," has had plenty of fun moments on her tour so far, including trying to twerk onstage, taking a selfie with her lookalike mid-concert and helping a gay couple get engaged.
