For Beyonce, it was a lip-sync of presidential proportions. Sure, it went off without a hitch, but despite the cold, both Kelly Clarkson and James Taylor still managed to sing their songs live.
This is the second time we've heard synced music at an Obama inauguration. In 2009, cellist Yo-Yo Ma and violinist Itzhak Perlman only pretended to play their instruments as John Williams' version of "Air and Simple Gifts" played on.
Perhaps the most famous and obvious of them all was Ashlee Simpson's appearance on Saturday Night Live in 2004. The wrong backing track started to play, making for some awkward television and an impromptu dance.
Who could forget the 80s and 90s lip-synch sensation Milli Vanilli? These guys didn't sing live AND had their Grammy revoked after a reporter revealed the voices on their debut album weren't theirs.
At the opening ceremonies of 2008 Summer Olympics, 9-year-old Lin Maioke captivated the world's attention as she sang the Chinese national anthem. One tiny problem. That voice wasn't hers. It belonged to 7-year-old Yang Peiyi. Rumors circulated that Peiyi wasn't cute enough to perform but had a better voice.
It just goes to show you can't always believe what you hear, but you can bet fans will be all ears when Beyonce performs at the upcoming Super Bowl halftime show.
