AceShowbiz - Heidi Klum forgoes a bikini top when she's sunbathing alone.
The German model credits her free-spirited upbringing for her attitude to nudity, and loves nothing more than sunning herself in teeny tiny bikinis.
Talking to Ocean Drive magazine, Heidi said less is more when it comes to her swimwear attire.
"I tend to not wear a whole lot of swimsuit when I am sunbathing. So I usually go for a tie-string bikini, something that has less coverage, and if no one is around, I'll wear only the bottom," she told the magazine. "I grew up being very comfortable with my body and very free.
"I grew up in a very free environment with my parents. We'd go to nude beaches. We're very open-minded, but you can't say that about all Germans. We didn't have a lot of money, so we'd go camping a lot and my parents chose nude campsites, so nudity became normal for me. I loved it."
Posing on the cover for the glossy mag's 25th Anniversary Swimsuit Issue, Heidi is snapped in just a pair of bikini bottoms from her Heidi Klum Swim range, part of her Heidi Klum Intimates offerings.
On the subject of getting older, the 45-year-old says she has no plans to stop living the life she loves.
"I see it like this: we only have one life. This is our life right now and our moment, and our moment shouldn't be over after a certain age. There's not a time frame for only being able to wear a certain thing or to be in love, to go out," she smiled. "Thirty years old is not the cap and then you have to hide yourself and not go dancing anymore."
