The parents of X Factor finalist Rhydian Roberts have slammed Sharon Osbourne for humiliating their son in public and being nice to him in private, they went as far to call her a “two-faced old harridan”.

“Sharon’s a hypocritical old harridan. She has the nerve to slag our son off in front of the cameras and then, when they’re in private, she tells him he sings beautifully and she hopes that he wins,” Rhydian’s father Malcom told the News of the World.

“The other day she even gave him a big hug off camera and told him she loved him. She’s completely two-faced. Rhydian’s still a young man and she’s messing with his mind quite unnecessarily. It’s doing his head in.”

His mother Angela added: “Rhydian told us Sharon Osbourne was winking at him while she was supposedly furious at him. She was ranting for the benefit of the cameras but it’s all a fake.”
