Did she, or didn't she? Claims that pop singer Beyonce lip-synced during her performance of the Star Spangled Banner at U.S. President Obama's inauguration have media abuzz. A spokeswoman for the U.S. Marine Band told one media outlet the singer opted for pre-recorded music at the last minute. But Beyonce's team has not commented on the issue. Later, the U.S. Marine Band backtracked saying quote, 'no one in the U.S. Marine Band is in a position to assess whether it was live or pre-recorded.'
