*Houghton

Chantelle Houghton, winner of Celebrity Big Brother in 2006, said doctors have informed her she will never be able to conceive naturally because of her extreme eating patterns.She was the first ‘non-celebrity’ to feature in the Channel 4 reality TV show and found her showbusiness lifestyle after her appearance difficult.

Miss Houghton said: ‘I’ve punished my body, and now it’s punishing me. Ultimately it’s my fault. I hate myself and can never forgive myself.

‘Because of my obsession with food and my crash dieting when I had bulimia, I’ve ruined my chances of having a baby naturally.

‘All the time I was making myself sick, I was thinking: “Yes, I’m getting skinnier.” I thought I was winning, but I was losing. It’s cost me the chance of a family.’
