X Factor cosmetic surgery fans Sharon and Dannii at loggerheads

Past X Factor judges Sharon Osbourne and Dannii Minogue are currently at loggerheads again, following the publication of an extract from Dannii's new autobiography. Titled Dannii: My Story, the book details the feud that emerged between the two cosmetic surgery fans during their time on the hit TV show. Dannii alleged that Sharon ruined her first night on the show and that the difficulties between the stars continued throughout the whole series. According to the News of the World, she wrote: "The rest of that first series was a rollercoaster of emotions. While I loved being a judge, I started to grow weary of Sharon and Louis's united front against me. "Though Louis and I are good mates these days, he would be the first to admit that back then he felt a sense of duty towards Sharon, taking her part in what had become a feud - albeit a one-sided one." While the discord between the stars was well known while they were working together on the X Factor, the trouble seemed to have died down in recent months. However, with news that Sharon's daughter Kelly recently took it upon herself to defend her mother over Twitter, it seems certain that the pair will remain on uneasy terms. While the two judges did not see eye to eye when it came to many things, they did both reveal a fondness for cosmetic surgery. Dannii had a boob job near the beginning of her career and has made use of a number of non surgical solutions since, including wrinkle relaxing injections such as Botox, while Sharon is famous for her fondness for appearance-boosting treatments. The feisty wife of rock legend Ozzy Osbourne has had a number of procedures over the years, including a face lift, tummy tuck and breast lift.
