Sharon Osbourne has reportedly been defacing pictures of Dannii Minogue on The X Factor set.
Sharon, well known for her feud with her former fellow X Factor judge, is said to have vandalized pictures of Dannii found backstage.
The two were on the show together in 2007 and there was no love lost between them.
Their war of words has continued ever since in the press and in their respective books.
And it seems Sharon's still not quite over it.
The Mirror newspaper claims that she and Louis Walsh have been acting like naughty school children and drawing penises on photos of Dannii which line the corridors of the studio.
A show source told the tabloid: “There is a huge penis drawn on Dannii’s head. Sharon and Louis 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 quit The X Factor the year after Dannii joined in 2008, saying the Aussie popstar was part of the reason behind her decision.
Dannii herself continued as a judge until 2010, while Sharon first returned to the panel for its tenth series in 2013 before making another comeback this year.
