The pair ended up rowing at the hotel’s plush £100-a-head China Tang restaurant, where Sharon had invited the show’s judges and producers out for a meal.

A source said: ‘Sharon’s face was the colour of her hair – she looked like she was about to explode. No one knew where to look as she effed and jeffed at him.’

‘She feels betrayed by Louis because, when she came back to the show, they had an understanding that they would help each other out. But Sharon feels humiliated that she was seen on camera pleading with him to help her out – and that he totally ignored her.’
It is reported that Sharon ‘marched down the hallway’ shouting ‘”You f****** ****. I thought we were friends. You’ve betrayed me.’
Producers reportedly tried to calm down the situation by placing the two judges at opposite sides of the table.

The show on Sunday was watched by nearly ten million viewers as Sharon pleaded with Louis not to dump Devonshire singer Shelley after she competed in a sing-off.
The decision was left in Louis’s hands after both Gary Barlow and Nicole Scherzinger voted to send Shelley home while Sharon supported her own act.
Boy band Kingsland Road came last in the flash vote on Saturday night and would have been the ones going home by default, had Louis voted for Shelley.
Sharon now only has one act left in the show, prison officer Sam Bailey.
