Singing “The National Anthem” at the Presidential Inauguration isn’t something a performer wants to screw up.

According to the U.S. Marine Band, the Queen of Pop lip-synced her performance Monday.  A source says Beyonce did sing live, but she pre-recorded a track to sing over.  Not that the Marine Band has much room to talk-  their musical accompaniment to the singer was also pre-recorded.

“Well, she had me fooled! She even pulled out the ear piece, like she was really into it and everything!” Sirius XM’s The Heat’s Deja Vu said in a Facebook post.

Kelly Clarkson’s rep confirmed her performance of “My Country Tis of Thee” was live.
