Violinist Natalie Holt hurled eggs at Simon Cowell during the UK TV show "Britain's Got Talent," which aired live last night to 13 million viewers (video below).
Holt is a respected musician who has worked with major orchestras and pop acts such as Gwen Stefani.
Holt, who was playing in the "Britain's Got Talent" backup orchestra, ran to the front of the stage and began her attack while two brothers (Richard and Adam) performed a serious operatic number.
"I basically took a stand against people miming on television and against Simon and his dreadful influence on the music industry," Holt told the Telegraph.
Holt auditioned for the "Britain's Got Talent" in 2012 with her band Raven Quartet, who distanced themselves from her funny stunt.
Holt apologized after the show via an official statement: "I want to apologize to Richard and Adam for overshadowing their performance. I’ve never done anything like this before and in hindsight I have realized it was a silly thing to do."
Popular VideoThis young teenage singer was shocked when Keith Urban invited her on stage at his concert. A few moments later, he made her wildest dreams come true.
Apparently, Holt committed the unforgivable sin, and was lashed out at on Twitter and Facebook.
Holt's ex-roommate X-Factor contestant Kitty Brucknell wrote on Twitter: "Just to make it clear…I’m absolutely disgusted that someone would do that – might have been funny for some, but those singers were amazing."
"And didn’t deserve their performance to be ruined like that. It was so unnecessary….and actually pretty cruel and stupid. I was there when she tried out for BGT…she seemed so normal?!?!'"
Amazingly, Cowell showed far more maturity than his angry supporters and tweeted in response to the incident: "I really don't like eggs."
A spokesperson for "Britain's Got Talent" told the Daily Mail: "Natalie Holt [age 30] 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.'
Judge Amanda Holden called Holt "a stupid cow."
Cowell thought Holt was part of the performance until the eggs came: "I thought it was part of the act, I thought they were throwing sandwiches."
Holt did get support from Piers Morgan who tweeted: "My vote goes to the egg-thrower. #BGT."
