Who's on Britain's Got Talent 2016 tonight? See the contestants on this evening's third Semi final line up, airing Tuesday night on ITV from 7:30PM.
Meet Boogie Storm, Simon Cowell's golden buzzer act on Britain's Got Talent.
This year saw Simon become the last of the judges to press the golden buzzer, waiting until a group of Stormtroopers hit the stage.
"Are you evil?" asked Simon but he got no response.
"Do you work for this Dark Lord?" quipped Amanda Holden in reference to Simon, getting equally little reaction.
The group then went on to perform a surprising upbeat dance routine to songs including Sax, Watch Me (Whip/Nae Nae) and Single Ladies.
And after lots of encouragement from the audience, Simon slammed the gold buzzer.
"It's no surprise that the real life Darth Vader voted for his troops," David Walliams reacted.
Simon Cowell concluded: "The dark side has taken over."
But can Boogie Storm replicate their success in the live semi-final tonight?
Britain's Got Talent 2016's third semi-final airs tonight from 7:30PM on ITV.
