Bust A Move

The ITV Britain's Got Talent panel was taken aback when members of the studio audience ran onto the stage. A dance performance caught the entire team by surprise during their unexpected number.

Ant and Dec were back as hosts as the search for Britain's next big thing continued. Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli returned as judges as they hoped to find another new talent to turn into a star. Social media star KSI stepped in for Simon during some acts.A young dance troupe from South Wales, Bust A Move, comprised of varying ages and only a single young male performer, Dominic, took to the stage in red outfits.

The group was accompanied by their parents who watched on from the audience seats. Dominic told the judges if they were to win they would spend all of their prize money on "sweets."

The kids kicked things off with an energetic performance, with little Dominic stealing admiration from Amanda and Alesha.

Their routine came to an abrupt halt when they moved to the edge of the stage and called out to their parents. Collectively, they screamed: "Alright, mums. Show us what you're made of."

The group's parents watching in the audience stripped out of their casual wear in favour of sparkly dance costumes and swarmed the stage.

Bust A Move

Bust A Move ran to the back of the stage, allowing their parents to take over the rest of the routine. As they watched on from the sides, the mums received a huge and positive reaction from the audience.

The judging panel took to their feet with Alesha screaming in disbelief as the unexpected switch up. When the performance came to an end, Bust A Move joined their parents for a round of applause.

KSI praised the group's energy and positivity. He said: "I loved every part of that and you guys had a great smile during it. Amazing."

Alesha said: "Can I just check these are genuinely your parents. We love the element of surprise on this show and you delivered in abundance. I can feel the passion in all of you. You are all superstars."

Bruno said they were a beacon of light and proved that dance can be for anyone no matter their age or abilities.

Bust A Move and their parents received high praise from the judges and moved on to the next round.
