Posh Spice, I believe has the most slip-ups. In one scene where the girls are being instructed by Mr. Step they all give each other eye contact and music starts playing. The camera cuts to a room scene and you can clearly see Posh spice start the choreography ahead of time but catches her mistake and stops. But then at the end when all turn to walk out, she does an extra step-thing. Am I the only one who caught that?
