Chantelle Houghton Chantelle Houghton has opened her heart...

And taken off her clothes.

But her revealing interview isn't about coming across as a sex kitten.

In this week's Heat magazine the reality star has stripped down to basic undies and is showing off her body sans make-up and sexy lingerie.

She also addresses the recent rumours linking her to Jordan's estranged hubby Peter Andre.

Speaking about her weight she said: "I have tried every diet there is, from body wraps and the Special K diet to just drinking water, but I know I have to eat healthily and go to the gym, because that's the only thing that works. 

"I've tried everything, apart from surgery and it can make you really unhappy about yourself."

Shockingly, she reveals the torture she endured to make herself skinny:Heat Magazine "I was making myself sick a lot, so food was just coming straight back out of me.

"I was literally drinking about eight of those litre-and a-half bottles a day. The water would fill me up."

She revealed: "My periods even stopped for a whole year. You know when that happens that you are messing about with the inside of your body. I want children and that can be affected too."

She also reveals she has quit glamour modelling, and admitted: "Looking back I can't believe the amount of make-up I used to wear. I don't even use fake tan anymore."

And what about the Peter Andre chat?

Chan reckons: "We're just friends, there's nothing there. We have the same management - that's the only reason I've been seen out with him.

"It's crazy to think anything is going on. The stories about us having secret dates are totally made up."

The full interview appears in this week's Heat magazine, on sale tomorrow.
