So now it's official, Beyonce did not sing live...

An inaugural official tells CNN: "She did not sing live. Because she didn't have time to rehearse with the Marine Band, she decided to use her recording with the Marine Band. It was all Beyoncé. She's actually a very good live singer.''

A source tells the NY Post, “Pavarotti has done it! It was freezing out and if she messed up just one note that would have been the story. She did sing. She just used a track.”

Beyonce is not the first and CERTAINLY not the only to lip sync at a big event...

Whitney Houston is believed to have lip-synced her impressive rendition of "The Star-Spangled Banner" at the 1991 Super Bowl. Her spokesperson at the time said she was singing, but her mic was turned off so viewers heard a prerecorded track.

Ashlee Simpson was caught lip-syncing on "Saturday Night Live" in 2004.

fast-paced dance routines. The pop star got caught in the act on her "Circus" tour in 2009.
