The 43-year-old model insists the fact she is 13 years older than her hunky boyfriend doesn't matter because they have such a good time together.

She said: "It's not about age.

"We have an amazing connection, we have fun together and we love each other. It doesn't matter what people say. As long as you know when you close your door in your own home, you have an amazing time together."

Though Heidi - who has four children, Leni, 12, Henry, 11, Johan, nine, and Lou, seven, with former husband Seal - is often pictured getting affectionate with Vito, she insists they aren't "putting on a show" with their public intimacy.

She insisted to Ocean Drive magazine: "I'm not doing PDA on the beach with tons of people.

"I go on a boat or I take a hike somewhere . . . If you would zoom out in the places where I'm with my boyfriend, there's nobody there . . . But to the outside world, it looks like we're frolicking on the beach having a show in front of everyone."

The 'America's Got Talent' judge is a "nudist" who has no problems stripping in front of other people.

She said: "I grew up going to nude beaches with my parents, so I'm a nudist. I have no problems with nudity at all. I'm very free. When I go to the beach, it's in a very remote place where there are not a lot of people, and I like to go topless.

"Everyone should do what they want to do, [even if it's] thigh-high stockings and a garter belt that shows a little bit when you sit at the dinner table.

"I don't think that's vulgar. I feel comfortable and don't care if someone sees my nipples necessarily -- it's OK to see the nipple! But not everyone feels comfortable with that."
