Robbie Williams has revealed that he is being treated for an illness which makes him lethargic and depressed.
The Take That singer told radio station Magic 105.4 that he first contracted the condition several years ago, but did not specify what it was.
According to Metro, Williams said: "I thought I was lethargic and depressed as a person. I thought that was my make-up.
"I found out a few months ago that I'd been ill, completely by mistake, and I don't want to go into the whys and wherefores, but what I had made you lethargic and made you depressed and I'd had it for years and not known. I'm on treatment for it. It's changed my life."
The full interview will air this Sunday between 2pm and 4pm on Magic.
