Someone has had about enough of Simon Cowell and decided to show him so by egging him during a live broadcast of the Britain's Got Talent Finale.

The young woman took the stage as part of the orchestra for an opera piece performed by contestants Richard and Adam Johnson. Carrying a carton of eggs, the musician began pelting the famously abrasive judge.

Although the camera operators attempted to change angels, they were unable to get the young perpetrator out of frame, according to the Daily News.

While the identity of the woman remains largely a mystery, The Mirror claims that the egg-thrower is a former contestant who held a grudge against Cowell.

Cowell's fellow judge Amanda Holden claimed that the woman was a "stupid cow" as she helped Cowell out of his yolk stained jacket before he went backstage to change, according to the Daily News.

"I told Sinitta the other day that I don't like eggs and I really don't like eggs, I'm sorry for you guys," Cowell told the performers, who kept singing during the incident, according to the Mirror. "I thought she was throwing a sandwich at me."

The young woman was quickly escorted off stage, but not before causing a significant disruption to he live broadcast.
