Simon Cowell has defended his decision to hire a house healer - saying they did a "great job".

The X Factor mogul, 52, whose shows in the US and in Britain have been under pressure in the ratings, hired the healer to visit his luxury Los Angeles home.

After getting some stick for the latest insight into his unusual lifestyle, he told his four million followers on Twitter: "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."

Simon, who enjoys twice-yearly Botox, regular colonic irrigation and intravenous vitamin injections to keep him looking young, according to a recent biography, added: "A new show we have been working on for a while got picked up this week. Spoooookeeeee."
