With no background music, Beyonce belted out the "The Star-Spangled Banner" at a press conference about her upcoming Super Bowl performance.
In a white long sleeve dress, the pop star walked out and kindly asked the media audience: "Will you all please stand?"
Before taking any questions, Beyonce then performed the tune she admitted to lip-syncing at the President's inauguration.
"I am a perfectionist," she explained. "And one thing about me: I practice 'till my feet bleed. I did not have time to rehearse with the orchestra. It was a live television show... Due to the weather, due to the delay, due to no proper sound check... I did not feel comfortable singing live."
