Furious Cheryl Fernandez-Versini has taken her long-running feud with Louis Walsh to new “toxic” levels.
And X Factor bosses are now struggling to keep the show going – as they “make Dannii Minogue and Sharon Osbourne look like best pals”.
Insiders revealed that Cheryl, 30, is refusing to speak to the Mayo man off camera or even be in the same room as him, and crew members have to keep them apart.

It comes as Louis, 61, continues to infuriate the ex-Girls Aloud star after she failed to stop him coming back to the show.
And an insider said: “If looks could kill, Louis would be a dead man.”
A source added: “The atmosphere has become toxic — she hates him with a real passion and it shows.
“It’s no secret that Cheryl didn’t want Louis on the panel, but since then he has been lording his victory and takes every opportunity to knock her.

“On the panel he has repeatedly slapped her down, and she has given him some poisonous stares in return.”
Sources told the Sun that “this is a pressure cooker and it’s only a matter of time before someone explodes.”
It came after Louis and Cheryl tried to prove they were back friends by posing for a selfie.
Previously Cheryl admitted she was loving everything about her X Factor return – except Louis.
