How shocked would you be if you saw a hundred girls who "randomly" burst out in dance in the middle of town?

Traffic stopped as the 100 girls broke into a performance of the iconic Single Ladies dance, to celebrate the announcement of an exclusive Beyoncé gig in November this year.

Anyone who buys a pack of Trident gum will be able to enter the weekly draw to grab one of the 13,000 free tickets for the one-off gig at the O2.

After watching the video, I'd love there to be a moment where all single ladies get together and perform this song when they're out - how cool would that be? It'd be THE common dance for single ladies if that ever happened - like line dancing!
