The five piece were dubbed the 'One Direction of dance' and made it all the way to last stage of the Sky competition, which was axed after its latest run last summer.
Dance troupe Boyband - made up of London students Corey 18, Mike 18, Dylan 18, Jaih 17 and Mikey 19 - were mentored on the show by former BGT champ Ashley Banjo, of dancers Diversity.
Their past success on Got To Dance isn't mentioned on the show this evening with some reports already branding it a 'FIX' in true BGT style.
However a spokesperson for the show insisted: “BGT is open to anyone, whether they are professional or amateur, irrespective of their past experience.
“Some acts have previously appeared on other shows, as is the case for many TV talent shows these days, but there are no rules that state this should prevent them from applying.”
We say best of luck to the lads, who impress on Britain's Got Talent tonight with a performance to Mark Ronson and Bruno Mars' Uptown Funk this evening.
