Diversity Juniors aka DVJ, are ones to watch out for on this year's series.
The dance troupe are masterminded by Ashley Banjo, who won the show with Diversity in 2009.
They beat Susan Boyle in the most watched series to date, with their victory seen by over 18 million viewers.
DVJ are a group of 10 school children, aged 10-18 years old.
"We've had Diversity support us and guide us so we can be here today," the group told the judges.
"This competition is now on fire," declared Alesha Dixon after their audition. "I can feel that you're all hungry and I love you."
With four yeses from the judges, the group made it through to the next round.
Ahead of this weekend's show, Alesha said: "We are spoilt for talent in the dance category this year; there are quite a few that I was pretty close to pushing my golden buzzer for. Then out came Diversity Juniors and knocked it out of the park.
"They came out and were incredible. Simon said they weren’t as good as the original Diversity, but I’d actually argue that the talent in that group is as good as Diversity when they first auditioned on the show."
Other acts in this evening's episode of Britain's Got Talent include circus performer Sascha Williams who performed a Rola Bola acrobatic act.
Plus, there was Matt Johnson, who performed an escapology trick, whilst locked and chained inside a tank filled with water.
Britain's Got Talent 2018 airs Saturday nights on ITV.
