Heidi Klum believes she has "lived many lives before"

She told The Times newspaper: "At work I'm very correct, straightforward and organised, but I'm super-messy at home. I'm a hoarder, so that's a slight problem. I love flea markets and I'm always looking for things that belonged to me in the past. They talk to me.

"I have this weird idea that I've lived many lives before," she says. "So I'll look at something like that antique clock over there and feel that used to be mine and I want it. Our house has become like a museum over the years."

Asked who she was in previous incarnations, she said: "I have always been men before -this is my first time as a woman."

The 'America's Got Talent' judge is fascinated by fortune telling and believes she is living out a prediction that was made when she was a teenager.

She said: "I get my palms, irises, feet, everything read. When I was 16 I had my future read and the astrologer said to me, 'Millions of people will listen to what you have to say. '

"But I hadn't even thought of being a model then or hosting Halloween parties. I just used to dream of having a big family, with a big house and garden, dogs and lots of kids. I'm lucky - I've got it all now."

Meanwhile, Heidi credits her toned physique to her active sex life with her 35-year-old musician husband.

Asked how she stays in shape, she said: "Sport en chambre is my favourite exercise - it sounds better in French. I have a younger husband. I also run around a lot, having four kids. I don't have an assistant, so I don't have people pack for me or carry my things, I do everything myself.

"I eat right, I never exercise too much or do heavy weights. People can push themselves too hard. I listen to my body. I have no back or knee pain and I have my husband.

"[Sex is] very good. My husband is my match."
