Old Men Grooving left the Judges open-mouthed in amazement when they busted out some SERIOUSLY good - and totally unexpected - moves on Saturday night.
We sent Stavros behind to scenes to catch up with the dancing dads to find out what their kids REALLY think, and why they think age is nothing but a number...
Mummy's boy Peter Lambert can't iron a shirt, but he's surprisingly good at spinning plates!
Can BGT Judge David Walliams beat Peter at his own game?
It's make or break time for David - find out what happens when he joins Peter on stage for a cheeky spin in our EXCLUSIVE unseen footage.
Judging by the sceptical looks on their faces, it's fair to say that the awesome foursome weren't expecting very much when Old Men Grooving slouched onto the stage on Saturday's show.
And they certainly weren't expecting what happened next...
The dancing dads drew gasps of amazement from the audience - and our Judges - when they launched into their energetic dance routine - we even spotted Simon, the toughest Judge of 'em all, enjoying himself!
Our BGT Judges were in fine fettle this week as they presided over the best - and the rest - of Great British Talent!
Saturday's show kicked-off with a sprinkling of Disney (black!) magic in the guise of 20-year-old Bristol singer Aaron Marshall, whose heavy metal take on Let It Go from Frozen left poor Amanda speechless... albeit for all the wrong reasons.
Equilibrium was soon restored when girl group Misstasia took to the stage though. Their smiley demeanours and sugar-sweet vocals had the audience singing along to Part Of Your World from The Little Mermaid, and even Simon looked impressed.
There are cries of foul play, but when it comes to our favourite double act's friendship, everything is just perfect thank you very much!
So perfect, in fact, they don't need anyone else... and especially not Stephen!
Oh I say!
The BGT Judges were treated to a little bit more than they bargained for during 27-year-old Lewis from London’s performance.
The Full Monty ain't got nothing on these boys.
Cold flannels at the ready ladies!
Four-piece girl group Misstasia had the audience enthralled with their oh-so-pretty performance of Part Of Your World from The Little Mermaid on Saturday night.
Does anything ever get these girls down?
Our man behind the scenes Stavros Flatley caught up with the little princesses to find out what inspires them, and what we can expect next from BGT's happiest act ever!
It's fair to say the Judges seem a little sceptical when 12-year-old schoolgirl Maia Gough reveals her musical idol is Whitney Houston.
But the young singer from South Wales has the entire audience on their feet following her powerful performance of I Have Nothing.
"It was mind-blowingly fantastic," says Amanda. Nuff said.
