It’s no secret that tensions between The X Factor judges sometimes reach boiling point.
And judge Sharon Osbourne didn’t exactly keep it quiet that she and former panellist Dannii Minogue were at war when they appeared alongside each other on the show back in 2007.
But things got so bad between the pair that music manager Sharon openly went around defacing pictures of singer Dannii for everyone to see.
A very cheeky Sharon defaced a picture of her arch-rival at London’s Fountain Studios, where the live shows are filmed, outside the judges’ dressing rooms.
Reality star Sharon, who has had nearly a decade-long feud with Dannii, drew a PENIS on her head in the photo.
A show source told the Daily Mirror: "There is a huge penis drawn on Dannii’s head. Sharon and Louis (Walsh) had a field day with it.
"They found it absolutely hilarious. It has been the talk of the studio.
"They are going to have to paint over it now but Sharon just didn’t want to have to keep seeing Dannii’s face every time she walked out of her dressing room."
Sharon and Dannii fell out during series four of the talent competition when the Australian singer had a fling with boss Simon Cowell.
Mrs O admitted that she and Louis felt "like gooseberries" as Dannii and Simon flirted backstage.
Sharon later wrote in her book Unbreakable that the time she spent with Dannii on the show was "unbearable", "intolerable" and "an odious chore".
Sharon gave music mogul Simon an ultimatum but he refused to choose between the two women and Sharon then left the show, leaving Dannii to continue as a judge until 2010.

Dannii has since given her account of the situation, saying Sharon and Louis were constantly out to cause problems for her.
She said: "Sharon announced to everyone who would listen that I was impossible to work with, that I was only on The X Factor because of my looks - not any visible talent or contribution to the entertainment industry - and Simon employed me only because he wanted to sleep with me."
