Sharon Osbourne is reported to have directed an angry and sweary rant at her fellowLouis Walsh after Sunday night's show.
Shazza is claimed to have been furious that her long-standing pal cast the deciding vote [uuid=6132441e-5015-4742-ba5c-b1a54ed0f176]which saw her second act leave[/uuid] the contest in two weeks.
Shelly Smith lost out in the sing-off against boy band Kingsland Road thanks to Louis' vote in favour of the group - and Sharon is reported to have let rip at him as they all enjoyed a Chinese meal after the show.
A source told The Sun: "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 was calling him every name under the sun. He just stood there trying not to laugh, which only made it worse. 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.
"Producers tried to calm things down by making them sit at opposite ends of the table in the restaurant."
And she is also claimed to have been cursing Louis before they'd even left the studio where the show is filmed.
A source told the paper she was heard yelling: "You f****** ****. I thought we were friends. You've betrayed me."
