Heidi Klum insists ''nothing has changed'' now she is dating her bodyguard.

The German supermodel started romancing Martin Kristen in September but says her new relationship hasn't had any impact on the routine of her kids - Leni, eight, Henry, six, Johan, five, and two-year-old Lou, who she raises with her soon-to-be ex-husband Seal.

She said: ''Nothing has changed for us. Not for the kids and not for anyone around us. It's not different for anyone than it was before.''

Heidi also admitted she has learned to be more guarded about her private life in the wake of the separation and now thinks she and Seal were too open about their marriage.

In an interview for German TV show 'RTL Exclusiv' which airs on Sunday (21.10.12), she said: ''I feel good. I've learnt from my mistakes a bit. That I've been very, very open with the relationship to my husband. And I think that will be more private in the future.''

The 39-year-old blonde beauty also revealed she is happy to go out with no makeup and has ruled out having Botox to halt the signs of ageing.

She said: ''I like going out without any makeup, absolutely!

''I take it as it is, even the wrinkles. My friends and acquaintances around me who like going to the Botox doctor - I don't know, I'm not that kind of person.

''Of course I see that I get older and I see my wrinkles. But I just accept it how it is.''
