"There's a bat!" she yelled to a crowd of over 25,000 people, flapping her arms and walking in a circle. "There's a bat there and it landed by your head! It landed right by your head!"

"Oh my God, it's a f**king bat. Welcome to Mexico," she joked. "It's true, I'm happy to be here, but a f**king bat, Jesus Christ!"

See her no-chill reaction, which was documented by a concertgoer via Twitter, below.

Luckily, her unexpected guest didn't keep her from putting on a stellar show. The British singer performed a mix of new and old hits, including "Rolling in the Deep," "Hello," "Someone Like You" and "Rumour Has It."
