'Idol' winner caught lip-synching?

Original American Idol winner Kelly Clarkson has been accused of a "heavy reliance" on backup tracks, according to MSNBC.

Despite insisting that she would "never" make use of the vocal aids, the singer roused suspicion at a recent gig in Pennsylvania.

"Kelly Clarkson live sounds exactly like she does on her albums - thanks to a heavy reliance on back-up tracks," a reviewer wrote in the Patriot-News."But the ‘American Idol’ winner needs to remember that when you pull the microphone away from your mouth, all singing should cease."
