Britain’s Got Talent: The Champions continues on ITV tonight - here's the fourth line up of contestants going head to head.
Britain’s Got Talent: The Champions brings together both Britain and the world’s most talented and memorable acts from past series of Got Talent.
Contestants from across the globe plus the past 13 years of BGT go head to head in the supersized version of the show, competing to be crowned the ultimate champion and walk away with a cash prize and coveted Champions Trophy.
In each of the five heats, nine acts will face off with two acts making it through to the grand finale – the first is a Golden Buzzer act chosen by one of the judges - Amanda Holden, David Walliams, Alesha Dixon and Amanda Holden - or Ant and Dec while the second is voted through by the arena audience.
The first episode saw Ukrainian sand artist Kseniya Simonova win the Golden Buzzer from Amanda while American daredevil duo Bello and Annaliese Nock won the superfan vote.
Week two saw German dog act Alexa Lauenburger win Ant and Dec's golden buzzer and dancers MerseyGirls win the audience vote while last week it was dancers Paddy and Nico who got the golden buzzer from David and illusionist Darcy Oake make the final with the audience vote.
Who will be next to make the final?
