BGT thrown into chaos as food fight breaks out among judges after Simon Cowell is covered in foam on live TV

SIMON Cowell got more than he bargained for during one of tonight's Britain's Got Talent performances.

One of the acts, Troll Dancers, delivered the bemused judge an unexpected surprise.

While most of the group performed an energetic dance routine, one member sprayed Simon from a bottle, covering his face in foam.

Afterwards, fellow judge Alesha Dixon remarked: “What have you done to our Simon? You cheeky, cheeky little Trolls.

“Before you did that, I was just going to say how well behaved children, they’re adorable.

“I have to say Trolls is a massive hit in many a household, I know my little Anaya will be at home having the time of her life.

“You did brilliantly well, the choreography was great, you took over the studio. You made it fun.

“I can’t believe you did that to Simon!"

She added: "I loved it, it was a colourful spectacle. Well done, Trolls.”

Bruno Tonioli commented: “You went for it! You’re naughty, naughty. I loved the chaos, I loved the dances, I loved the fun.

"Actually, the choreography and staging was brilliant.”

Simon himself said: “I was just thinking how sweet you were. Look, at least I don’t look stupid.”

He added: “You’re very naughty, who put you up to that? Was it these two?”, pointing to presenters Ant and Dec.

Ant and Dec denied responsibility but showed they had enjoyed the act's surprise for Simon.

Fortunately, there were no hard feelings as Simon declared the group to be “brilliant”.

Meanwhile the group member in question offered up an apology, telling the panel, “Sorry, Simon. We love you all.”

Simon replied: “I love you too, don’t worry about that.”

Viewers also loved Troll Dancers’ antics, taking to X (formerly Twitter).

One wrote: “I loved the chaos! You could tell they were having the time of their lives tonight.”

Another added: “Totally brilliant.”

Britain's Got Talent airs at 8pm on ITV1 this week, with Sunday's final airing at 7.30pm.
