In a move likely calculated to put an end to all the chatter over her lip-synced performance of the National Anthem at President Obama's inauguration last week, Super Bowl halftime show performer Beyonce Knowles opened a press conference Thursday with a show-stopping rendition of the Star-Spangler Banner. Singing in front of a massive video screen that displayed an image of the American flag, Beyonce finished her performance and asked the assembled reporters, "Does anyone have any questions?" Though she admitted to lip-syncing her performance on Inauguration Day, Beyonce assured the crowd that she plans to perform live on Super Bowl Sunday. Watch Beyonce's live performance below:
