On stage, Britney Spears is a veritable super hero, brimming with confidence and the powers that comes along with being a pop star.

How unfortunate then that her cool demeanor was cracked by something as simple as bad weather. During an X-Factor taping in Greensboro, NC, she gets scared shitless when lightning and thunder strike the set.

"Are you okay?" Demi Lovato asks, after Britney screams a handful of times.

"Oh my god!" says Spears, "That [expletive] is scary as [expletive]."

Then she apologizes.

"I spit all over you, I'm sorry," she tells Lovato. "We need to get outta here."
