SHARON Osbourne will be spending the weekend in Ireland after jetting in to film the X Factor with Louis Walsh.
The flame-haired personality (57) has flown in this morning in a sensational return to the show to help the Westlife manager whittle down his finalists.
And although programme bosses have tried to keep the location a tightly-guarded secret, the Herald can reveal they have chosen glitzy Adare Manor as the venue.
The crew will spend two days filming at the venue, which played host to a bevy of stars this summer including Tiger Woods and Michael Douglas for JP McManus' Pro-Am.
Sharon, the wife of hellraising rocker Ozzy, will help Louis pick out the finest acts in his group for the 'judges houses' stage of the hit show. A ring of security is in place around the luxury hotel to ensure the film takes place discreetly and the finalists' identities are protected.
Sharon's daughter Kelly let the cat out of the bag about her secret return after writing on her Twitter page: "My mummy just came to see me on set before she jets off to Ireland to film X Factor with Louis!!" She then added: "Looooove Ireland I wish I was going with her!"
Sharon famously quit the show in a blaze of publicity in 2008 after four series working on the show. She was replaced by Cheryl Cole but later admitted that it was her dislike for Dannii Minogue that led to her leaving.
After three years as the lone female judge on the show, Osbourne was openly annoyed when Minogue, who is 19 years younger, joined the panel in 2007.
"I left because of Dannii Minogue. Simple as that," she said. "I didn't enjoy working with her at all and the prospect of spending six months sitting next to her, I thought 'my life is better than that'."
She always stayed good friends with Louis in the wake of her leaving the show - and he asked for Simon Cowell's permission to bring her back.
Mayo mogul Louis has admitted he came close to walking out when he discovered which category he had been given to mentor this year.
"I can't say who I have but I'm not happy. I nearly walked last week when they gave me my category," he said.
He mentored the groups for four of the last six series of the X Factor. Last year, although his act Jedward failed to reach the final, they still proved to be the biggest success story of 2010.
