The Britain's Got Talent judges loved Boogie Storm at the weekend but they weren't the first set of dancing Stormtroopers is on the show.
The original ones appeared back on Britain's Got Talent more than five years ago now in 2009.
They were a part of dance act Darth Jackson who performed as a Michael Jackson impersonator while dressed as Darth Vader.
In the live stages, Darth Jackson performed to a string of Michael Jackson songs along with a group of Stormtrooper dancers.
Interestingly, Simon Cowell HATED the act and buzzed in the semi-final show.
He complained: "Where did you dream up his monstrosity of a routine? You and people in white suits doing a horrible version of Thriller."
After being told the "people in white suits" were Stormtroopers by Ant and Dec, Simon replied: "Whatever they are."
Simon gave quite a difference reaction to Boogie Storm on Saturday night after they did pretty much the same thing, albeit with no Michael Jackson and Darth Vardor crossover.
The performers got a golden buzzer straight through to the semi finals from Simon, who quipped: "The dark side has taken over."
With the golden buzzer, Boogie Storm have gone straight through to the live shows later this month.
They're joined by Amanda's golden buzzer, 12-year-old singer Beau Dermott, Ant and Dec's choice, 14-year-old singer Jasmine Elcock, Alesha Dixon's act, 100 Voices of Gospel choir and finally David's golden buzzer performers, singing duo Ian and Anne Marshall.
But while all the golden buzzers are now gone, the auditions continue: Britain's Got Talent is back next Saturday night on ITV.
