Carrie Underwood is making the media rounds in support of her new album, Cry Pretty, which dropped on Sept. 14.

Last night (Sept. 13), Carrie was a guest—and performed—on The Tonight Show as Jimmy Fallon hosted the program from Central Park in front of 1,500 fans.

During her sit-down chat with Jimmy, Carrie revealed the details behind the illness that forced her to cancel two shows in England on Sept. 8 and 9.

“I don’t cancel shows—I will drag myself onto the stage and perform if I have the flu or whatever,” Carrie told Jimmy. “In the UK, we had to cancel a couple of shows. Basically, I got a viral thing and I woke up and I had vertigo and I could not stand up and it was crazy. I ended up in a German hospital for three days.”

Carrie, who is a vegetarian, quipped that the only German phrase she learned was “no meat, please.”

After the chat, Carrie performed the television debut of her new single, “Love Wins,” which you can watch below, as well as her sit-down chat with Jimmy.
