Ashlee Simpson has responded to that embarrassing performance on Saturday Night Live when a computer error meant the vocals she was performing (ie miming to) didn't match the song her band were playing. It was embarrassing because it revealed she was miming on the show.
Speaking to MTV yesterday, Simpson explained that she suffered from a chronic condition of "severe" acid reflux disease - a condition in which the stomach's liquid content regurgitates into the oesophagus (lovely) - and that it was that which caused her to lose her voice on Saturday. After her doctor advised her not to sing, Ashlee and her manager/father Joe Simpson decided to go ahead with her Saturday Night Live performance but with a lip sync track.
Ashlee continued: "It's so embarrassing because it sucks. The total situation was a bummer. I made a complete fool of myself."
Her father, meanwhile, told LA radio station KIIS-FM: "Just like any artist in America, she has a backing track that she pushes so you don't have to hear her croak through a song on national television. No one wants to hear that. Every artist that I know in this business has had vocal problems at some time, from Celine [Dion] on down. So you've got to do what you've got to do."
