Simon Cowell, Dannii Minogue fail to show for Sharon Osbourne's Christmas party

Simon Cowell and Dannii Minogue failed to turn up to fellow 'X Factor' judge Sharon Osbourne's Christmas party, it has been reported.

55-year-old Sharon welcomed in the festive season with a swanky party at the DKNY store in London.

Sharon's pal, Louis Walsh, 55, was the only other X Factor judge to make an appearance, reigniting claims that Dannii and Sharon hate one another.

A source said: "Dannii had other commitments and knew it was Sharon's party so didn't want to deflect from that.

"The last thing Dannii wanted was to answer more questions about her relationship with the other judges.

"So she sensibly stayed at home drinking her favourite liquorice tea. But a few folk did raise eyebrows that she wasn't there."
