The show creator has apparently hired a healer after becoming concerned about the growing tension between Gary Barlow and Louis Walsh.
Healer Hazel Taylor has visited the studio to try to put an end to the negative energy and give the contestants a boost, the Daily Star reports.
"We need all the help we can get. You can cut the atmosphere with a knife so the healer was brought in to try and see off the bad energy and bring the fun back," a source said.
"Hopefully, all of the last week's negativity will be over and we can have a laugh again."
Barlow fell out with Walsh after he sent last week's result to Deadlock, meaning Barlow's act Carolynne Poole was sent home ahead of controversial contestant Rylan Clark.
Barlow stormed off stage after the result was read out and the pair still weren't speaking at a recent crisis meeting attended by the judges and producers.
The duo returned to the studio for yesterday's soundcheck, where they "remained professional", according to sources.
"The atmosphere was still a bit strained between Louis and Gary at soundcheck yesterday. Everyone is waiting to see what happens tomorrow and to find out whether they'll be friends or not," an insider said.
Cowell has previously admitted to hiring an American healer to cleanse his own home, claiming that the house "felt different" afterwards.
