Britney Spears may lip-sync her way through her two-year Las Vegas residency.


The New York Daily News reports that the 31-year-old pop superstar will not sing live during her 90-minute "Piece of Me" Vegas shows, which kick off at the Planet Hollywood Resort & Casino Friday, Dec. 27. Spears is set to showcase her greatest hits as well as tracks off her new album, due out Dec. 3.


“Britney does not sing," a source told the newspaper. "She is being paid a lot of money to lip-sync. Her fans are none the wiser, but it is disingenuous of her to take their cash and not deliver a proper performance.”


“She hasn’t sung live for a couple of years,” the source added. “If the crowd thinks they are being cheated then there is likely to be an uproar, but then again look at the success of Cirque du Soleil’s Michael Jackson shows. The performers in that production don’t sing live, and it has been a runaway success.”


Gossip Cop, however, says the report is totally false.


The website claims the "supposed insider" has been trying to pass off the "bogus rumors" to multiple news outlets for weeks. A source close to the singer allegedly told the site “Britney will be singing" and has been in vocal training for months now.


This is not the first time the "Work Bitch" star's vocals have come into question. Earlier this year, rapper Eve suggested Spears didn't even sing in the studio for will.i.am's "Scream & Shout." Her publicist quickly quashed Eve's claims.
