The star is due to return to the show later this year.

Sharon Osbourne has landed herself in some serious hot water after attacking Simon Cowell on a radio show this week. Sharon is due to return to the X Factor for the live shows later in the year but now reportedly faces being dropped from the show entirely after tearing into boss Simon on Howard Stern’s radio show in the US. Speaking of replacing Stern as head judge on America's Got Talent, Sharon said:

“Simon loves to be on TV,” she said. “And he wasn’t on TV in America and he’ll do whatever he has to do to get his f***ing fat face on TV. “I like Simon, he’s been good to me but he’s a f***ing pain in the a**e.”

However, her most shocking statement came when host Howard Stern asked Sharon what she would do if they were on a boat with Simon and it began to sink.

“Oh, we’d put a f***ing brick around his neck and throw him over.” “And drown him?” Stern asked. “Oh, I will drown that motherf***er. Absolutely, he’s gone.”

Sharon is due to return to the X Factor judging panel for the live shows and says that she won’t be holding back this year.

“I don’t have to have those kids singing in my face. Those little s**ts. They all suck. “The thing is, it is the end of my contract now, it is like no holds barred. It is like get the f*** off the stage.”

Sharon went on to attack the new judging line-up which includes Louis Tomlinson, Robbie Williams and his wife Ayda Field. However, she joked about getting fired after the interview aired asking Stern is he would be “giving me a job when I get the sack?” A source close to the show now says that the interview has left Simon fuming.

“It seems untenable for her to continue on the X Factor given this attitude,” they told The Sun. “Simon will be absolutely furious.”
