The X Factor tycoon stunned fans when he called in a healer to purify his luxury home in California and drive out any negative energy.
But he's taken to microblogging website Twitter.com to defend his bizarre decision, telling followers, "I have to say the house healer did a great job. I did it because if you believe something can make you feel happier then try it.
"I wasn't trying to get rid of bad things but I believe your home should be peaceful. And two people came round today and said the house felt different. So you never know."
