It seems that Avril Lavigne still has a bee in her bonnet about Ashlee Simpson's embarrassing performance on Saturday Night Live.

She told the New York Post, "In a way it was good because it showed that people are doing it on TV all the time.

"I've never lip-synched once in my life. I never will. I'm a singer, and I sing live. That's what music is about. I see lip-synching all the time at awards shows, and it makes me think, how sad. It's a disgrace that this is what music has come to."

When asked to name names, the Canadian singer complained, "People like Hilary Duff. I've never heard her sing live. Each time I've seen her perform, she lip-synchs. She sings to tracks and they either amp her vocals very low or she just doesn't sing at all. You don't deserve to be there if that's what you do."
