Ant and Dec present a special version of the talent show, in which stars from the past 13 series of Britain's Got Talent compete against winners from versions of the programme from around the world to impress the viewers and judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams. Each week, two acts will make it through to the grand finale. The first is a Golden Buzzer act chosen by one of the judges, or Ant and Dec, while the second is voted through by superfans in the arena audience.
