Britain's Got Talent Lives: New Twist and Guest Performers
The live shows start next week with Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams
Each night, eight of the the final 40 semi-finalists will be performing live in the hope of impressing the viewers at home and winning the all important public vote.
The two acts with the highest votes will then proceed onto the live Grand Final on Sunday 4th June, with a chance of winning a life changing £250,000 and a spot at this year's Royal Variety Performance.
This year the viewers will vote through the top two acts, the judges will not have a say in who goes through.
And in an additional twist, at the end of the week there will be a Judges Wild Card allowing our formidable foursome, Simon, Amanda, Alesha and David, to select one act of their choosing to go through to the live Final.
Guest performers have been revealed as ex Fifth Harmony member Camila Cabello, Alfie Boe and Vera Lynn as her very own hologram, the cast from Bat Out of Hell: The Musical, X Factor's 5 After Midnight and BGT reigning champion, magician Richard Jones.
The live Grand Final will also be a spectacle of talent, with the UK's biggest girl group Little Mix and the UK's biggest dance crew Diversity gracing the stage.
Britain's Got Talent Live semi-finals air Monday 29th May to Friday 2ndJune at 7.30pm on ITV. Followed by Britain's Got More Talent, also live, on ITV2 at 10pm.
