Ashlee Simpson explains 'SNL' fiasco

Ashlee Simpson has come up with a new excuse for what happened on Saturday Night Live this weekend. Apparently it was all down to heartburn.

She says that 'acid reflux' had damaged her vocal cords earlier in the day and so she had to rely on the support of a backing track for the performance. This is news, however, since originally she said it was her band's fault for playing the wrong song.

"I had severe acid reflux, and the day of Saturday Night Live' I had completely lost my voice. It's crazy, but you move on.

Things happen. I'm a human being," she announced at the 2004 Radio Music Awards in Las Vegas on Monday.

Having been criticised by fans, Ashlee explained that: "I can't cancel something like SNL.

It was silly of me to do it, silly of me to blame the band, I was just so embarrassed."
