Simon Cowell caused an uproar on Britain's Got Talent when he mid-way through ventriloquist Jimmy Tamley's performance - leaving the baffled comedian unable to finish his act.
Viewers at home dubbed it 'car crash TV' and speculated if the reason behind Simon's stubborn exit was a sour-mood they'd claimed to pick up during the night.
While others wondered if it was down to Simon's apparent 'tension' with co-judge David Walliams - with the pair
However, a TV insider has claimed there's a more personal explanation behind Simon's apparent upset.
The source claimed explained that Jimmy had accidentally niggled an injury of Simon's and he felt he need to take measures to stop any unintentional damage.
They claimed: “It turns out the reason Simon left the stage was due to an old ski-ing injury. Jimmy grabbed hold of Simon’s knee but, understandably, won’t have realised about Simon’s old injury when he wanted him to do the can-can.
"So Simon had to take the lead to stop any embarrassment! Backstage, everyone has been giggling - and Simon thinks it was a great TV moment!”
They added: "Simon is absolutely fine. He’s been laughing about it. There’s been lots of laughter in the dressing room, with a few production members jokingly acting with their tails between their legs! But Simon saw the funny side."
The talent show mogul had stopped the show on Thursday night when BGT contest Jimmy pulled him on stage in a segment that some viewers called "car-crash TV".
Simon looked less than impressed as he was forced to wear a mouth-piece while Jimmy cracked jokes about him and David's imagined relationship.
Things came to a standstill when Simon was asked to do a can-can dance with David and Jimmy grabbed hold of his legs.
A furious Simon stormed off the stage in a rage, yanking off his mask as he refused to complete the task at hand.
Poor Jimmy looked awkward as he tried to finish off his act while David did his best to wrap things up.
Luckily Simon had a change of heart and wandered back on without the mask and willingly went into the waiting cargo box that was on the stage alongside his fellow judge.
Afterwards Alesha Dixon joked that Jimmy should have used Ant and Dec as his assistants instead.
It's not the first time the judges have caused drama by joining in with performances.
On Monday night, Amanda Holden shouted out 'F***' during the live broadcast after she took part in a spooky act by magicans The Haunting.
The stunt received over 100 complaints to Ofcom and could face a full investigation.
Britain’s Got Talent airs live all this week on ITV at 7:30pm.
