Beyonce is to play a special free concert in the UK this winter, in conjunction with a brand of chewing gum.

13,000 fans will watch the R&B star perform at the London O2 Arena on November 15, by winning tickets from Trident.

Fans hoping to score tickets must first purchase a pack of Trident gum and then enter the last 4 digits on the barcode at Tridentunwrapped.co.uk. Starting on April 20, until May 31, the gum company will give away 1,000 tickets each week.

Any flavour from any outlet will be valid so no need to look out for special packs.
