Simon Cowell is reportedly furious after his egging during the Britain's Got Talent 2013 final.
While the music mogul was quick to joke about the incident on Saturday night, the show's security team weren't in for such a laugh.
The Daily Star reports that Simon was far from happy that the musician was able to storm the stage and pelt him with eggs before security knew what was going on.
“Cowell was absolutely furious that it appeared to be easy for her to waltz on stage and shower him in eggs," a source claimed. “During the break he stormed backstage and told one producer that she could have had a gun.
“He wasn’t so bothered about being hit with an egg but he was furious that the welfare of not only the judges but the contestants and the audience could have been at risk.”
However in a statement released by the show after the final, Natalie said: "I want to apologise to Richard and Adam for overshadowing their performance. I’ve never done anything like this before and in hindsight I have realised it was a silly thing to do."
A spokesperson for Britain's Got Talent added: "During tonight’s show an incident took place during the finale of Richard and Adam’s performance.
"Natalie Holt was part of the backing group for their performance and as a result of her misguided actions the police were called. However, we have decided to take no further action at this stage."
