Celebrity Big Brother star Chantelle Houghton has revealed she had doubts about her marriage to her fellow contestant Preston just days after their lavish wedding ceremony.

The couple married last August after meeting on the reality show earlier in the year but announced their separation in June.

Chantelle, a former Paris Hilton lookalike who appeared on the show as a fake celebrity, has now told the News of the World: “On the day of our wedding I felt 100 per cent I’d made the right decision. I was totally and utterly in love with Preston. It WAS the best day of my life.”

“But on the fourth night [of our honeymoon], he took me out to dinner and I suddenly felt really upset. The doubts had already set in.”

“I found we really didn’t have anything in common and were on completely different wavelengths. All of a sudden I felt ‘This is forever.’ And it scared me. It felt like a weight around my neck.”

“He was so wrong for me and I was so wrong for him. We were like from two different planets. I knew he wasn’t the person I wanted to be with. We just irritated each other and constantly rowed. He’s just not my kind of guy.”

“I ended up on the verge of a nervous breakdown. I was drunk most nights. I’d drink a bottle of wine, sometimes two, because I was so unhappy.”

“I also started scoffing bags of crisps and chocolate. I stopped doing exercise and just watched TV. When I looked at my naked body in the mirror I hated it - so pale and overweight. I didn’t recognise myself and felt disgusting.”

“That’s when I started making myself sick. Preston was regularly taking me out to posh restaurants and I’d have soup to start, then a big bowl of pasta followed by chocolate cake and cream.”

“I did enjoy it but as soon as I finished I’d feel guilty, lock myself in the toilet and stick my fingers down my throat. It was the same at home.”

“I hated making myself sick after food binges and knew it was bad for me. So I just lived like a hermit at home and stopped eating.”

“Some days I ate nothing. I must have lost over two stone as I dropped from size 12 jeans to a size eight. My mum got very concerned but I was proud I’d lost weight and thought I looked better.”

“In the end I decided to bounce back on my own [without counselling as her doctor advised]. I began eating sensibly again and started having fun with my mates. Now I’m back to a healthy 9 stone and feel great.”

“I’m so much happier being free and single. I got married far too young. I haven’t dated another man since the break-up and I’m not looking for a boyfriend. I really dont think I’ll ever marry again or have children. I don’t want the responsibility.”
