Heidi Klum is living proof that you can still look beyond amazing at any age, and her newest photos for her lingerie ad are the perfect example.

The 42-year-old supermodel has shared a few behind-the-scenes photos from her latest shoot for Heidi Klum Intimates, People has exclusively reported.

She has revealed how she looks fit all the time and what's on her mind while she's doing photo shoots like this where she's posing in very little clothing.

When it comes to staying in such great shape, "I like looking fit all the time - not just for a shoot - as you never know when your clothes come off!" she told People. "It's a big part of my job to make sure that I'm fit on a regular basis."

She stays in shape by drinking plenty of water and eating really healthy. With her busy schedule, it's hard to have a normal sleeping pattern, but she tries to sleep eight hours a day. She also goes on the treadmill two to three times each week.

When it comes to posing, her years of experience have taught her so much, especially not to overpose.

"No overarching, duck faces or strange poses so it doesn't look like you are trying too hard," she says. "Even though [photographer] Francesco Carrozzini is behind the camera, I look into the lens and I think about my boyfriend."

She has been dating Vito Schnabel, who is a 27-year-old art dealer in New York City, for more than a year now. She claims that Carrozzini has "a way of making everything look effortlessly sexy," so he's an amazing photographer to work with.

When she first announced that she was working on this intimates line back in October, Klum told People that she never gets self-conscious in front of a camera nearly naked. "When you've done it for so many years, it's kind of like riding a bike."

Yesterday, Klum showed off her body, proving why she has nothing to be self-conscious about, with a topless photo from the shoot and the simple caption, "@heidiklumintimates." There, you can see the lingerie line's entire collection and all the official photos of Klum modeling it.

The intimates line launched earlier this year and can be purchased here.
