'Oh Bey can you sing…' - Beyoncé 'lip-synced' Obama inauguration anthem

Beyonce Knowles reportedly lip-synced the American national anthem at Barack Obama's inauguration on Monday.

The 'Halo' hitmaker - dressed in a demure black dress with emerald earrings - sang 'The Star Spangled Banner' in Washington DC immediately following the president's swearing-in and speech but the audio is said to have been pre-recorded amid reports she only had one night to rehearse with the band before the performance.
