Beyonce lip-synched the national anthem at President Obama's inauguration to a pre-recorded backing track, The Times (£) reported.
A spokeswoman for the Marine Corps Band, who accompanied Beyonce, reportedly said the singer decided to rely on the studio version shortly before she was due to perform.
She said: “We did pre-record it and it was Beyonce’s decision at the last minute to go with the pre-recorded version. We pre-recorded all music as a matter of course and have done since time immemorial."
Beyonce "lip-synched" the national anthem at President Obama's inauguration because she did not have time to rehearse with the band.
A day of grand political theatre lies ahead, but President Obama knows his history and will be steeling himself for a turbulent second term.
Presidential inaugurations are normally highly scripted events, but things don't always go according to plan.
