Sticking with BGT tradition, there is a wildcard act for this year's final and the identity of the lucky performers has now been revealed.
Just like in previous years, the fact that only two acts can go through from each of the five live semi-finals, means that many fan favourites and judges favourites don't make the cut.
The Britain's Got Talent wildcard gives the judges the chance to hand a lifeline to one of the eliminated acts and, after only being drafted in at the last minute to compete in Friday's semi, this year's wildcard has been handed to dancing duo Libby and Charlie.
Hosted by Ant and Dec, the Britain's Got Talent final sees 11 acts take to the stage, each battling it out to win the top prize - £250,000 and a spot on the bill of the Royal Variety Performance 2019.
Dave and Finn, Flakefleet Primary School, 4MG, Siobhan Phillips, Colin Thackery, Kojo Anim, Ben Hart, Mark McMullan, X, Jonathan Goodwin and Libby and Charlie will perform one last time for judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams.
On the night, it will be down to the public to decide who is crowned the winner.
Also taking to the stage will be former winners Diversity who will present a fantastic new high-energy dance performance and superstar singer Susan Boyle, who will duet with Michael Ball on A Million Dreams.
