Ellen Degeneres had Taylor Swift rolling around the floor laughing on Friday - after the comic spooked the singer during a prank for her talkshow's Halloween special.
The Love Story hitmaker was a guest on DeGeneres' talk show in preparation for Saturday's ghoulish festivities.
And the funnywoman started the scares early by jumping out at the blonde singing sensation when she least expected it - as she made her way to the bathroom.
But the spooking almost left Swift with an injury, after she collapsed to floor in fear following DeGeneres' prank.
Swift soon recovered from the scare - but still couldn't get to her feet because she was laughing so much.
The pair hugged, with DeGeneres telling her audience, "I was worried there when she fell and hit her knee, but I thought. 'Ahh, she's young, she'll be fine!'"
