Beyonce hasn't given much away about her performance at half time during Sunday's Super Bowl - other than promising she'll be singing live. The singer admitted miming at Barack Obama's inauguration because she hadn't been able to rehearse properly.
She says there won't be a repeat of that in New Orleans during the game between the Baltimore Ravens and San Francisco 49ers.
As Beyonce makes final preparations, a clip has appeared online of one other thing she should avoid doing - handing the microphone to the crowd and asking them to sing along.
As a past performance proved, that can mean the song falls rather flat.
