Rylan Clark has revealed that he was hospitalised "for safety reasons" last year as he dealt with the breakdown of his marriage.
Last June the presenter announced that he had split from husband Dan Neal after six years of marriage and took four months off all of his TV and radio projects as he dealt with the fallout.
Now Clark has revealed that he became "quite ill" during that period, so much so that he was admitted to hospital to receive professional care.
"I'd got to the point where I didn't know if I wanted to come back," he told The Observer. "Or whether I would be able to do this job again. I'd got... quite ill.
"I went down to just over 9st and I'm 6ft 4in. It got bad. Like, very bad. And I didn't think it would get better. I needed help.
"I did not know myself at certain points. I was having thoughts and doing things that made me... fucked up, for want of a better word. I didn't understand why I was doing that to myself. So, I went away for a bit."
Asked if he went to hospital, he replied: "Yes. For safety reasons. It's really strange talking about this, because I've not even spoken about it to my friends. I just never thought I could get that ill."
Clark continues to present a Saturday afternoon show on Radio 2 and has also launched his own reality-themed podcast, Ry-Union.
