Taylor Swift appeared on The Ellen Show with Ellen DeGeneres on October 29th and got a bit more than she bargained for.

Apart from the interview with Ellen, which you can check out here, Ellen also played a prank on Taylor in the spirit of Halloween.

Ellen sent Taylor into a fake dressing room with cameras in the bathroom where she waiting hiding to jump out at Taylor and scare her. Taylor hits the floor super hard when it happens – we hope she didn’t get hurt!
