After all the praise and excitement of how great Beyonce sounded singing the National Anthem, the cat was let out of the bag: it was all fake. Beyonce lip-synced her performance of the National Anthem at the inauguration ceremony.

In an of itself, the performance was phenomenal, but them there were rumors rumbling shortly there after. People who were professional singers were commenting that the singing didn't look live. Then there were some reporters who commented in social media (but didn't report) that the Marine Corps Band wasn't playing. it was later reported by The Times UK that:
it was evident that the band wasn’t actually playing during the song—even though band director Colonel Michael J. Colburn was conducting energetically and the band members mimicked blowing into their instruments. Separately, at one point during her performance, Beyoncé removed her earpiece.

While this performance was compared to Whitney Houston's "Star Spangled Banner" performance, the biggest hint that this performance was one of illusion, came from Beyonce herself.

The day before the event performance, she posted a picture of herself in a recording studio with members of the Marine Corp. Band.

Take a look at the video and see if you can notice the difference.

A spokesperson for the Marine Corp Band was quoted about Beyonce's lip-syncing:

"We don't know why Beyoncé decided to use prerecorded music. All music [for inaugural ceremonies] is prerecorded as a matter of course, and that's something we've done for years and years. The Marine Band did perform live throughout the ceremony but we received last-minute word that Beyoncé wanted to use the recording."

The spokesperson also added that everyone knows Beyoncé is a gifted singer, and her decision has no bearing on her musical ability.
