Heidi Klum poses with son Henry and daughter Leni for Paper Magazine cover

The genes run strong when it comes to Heidi Klum and her children Henry Samuel and Leni Klum.

The group appears on their first magazine cover as a trio, modeling for Paper Magazine’s latest issue.

On the cover, Klum wears a pair of pink trousers and matching pink cardigan, sitting on a bronze bear statue in front of Leni, 21, who wears hot shorts that are styled with polka dot tights and a contrasting striped tee.

Meanwhile Henry, 20, stands behind them in all white, smashing a pineapple in mid-air with a baseball bat.

The brightly-colored shoot continues with a sartorial mashup, including Leni in striped boxers and knee-high socks, lying beside a kiddie pool her red carpet gown-wearing mother fills with a water bottle.

In another, Henry jumps in the air next to a dining room table that Leni stands on top of while Heidi squirts ketchup and mustard out of bottles while wearing a green skirt suit.

The models also pose together in a bathtub, looking up at a camera suspended above them.

Klum’s blended family is gearing up for a two-part reality series “On and Off the Catwalk,” which Paper describes as chronicling the supermodel “at the peak of her prowess, while also shadowing Henry and Leni’s own burgeoning modeling careers.”

“It’s trotting along to all of our different business ventures, so to speak,” Heidi said, adding, “Nothing is really staged.”

She shares Henry — as well as son Johan, 19, and daughter Lou, 18, — with ex-husband Seal, who also adopted Leni in 2009. Leni’s biological father is Italian businessman Flavio Briatore.

The “Germany’s Top Model” host also talks about how the modeling industry has changed over the last two decades, especially when it came to the treatment of a woman’s body.

“You didn’t see a lot of pregnant women on television [20 years ago]. It was a big thing at the time. I was pregnant with all my kids always on the show, and it was a challenge for me, because pregnancy clothes were really hard to find at the time,” she shared.

The 52-year-old continued, “I remember I had one client. When I was pregnant, they did not want to work with me anymore. They thought that I was not sexy anymore, because I was now a mother. I was defined before children as being a sexy woman, and now with a child, as being a mom. That I no longer deserved to have that, that…” to which Henry finished, “title?”

While Heidi, Henry, and Leni have never before appeared in a cover shoot as a family of three, the children have begun to take the modeling industry by storm just like their veteran mom.

Henry, who made his modeling debut on the Lena Erziak Haute Couture runway last January in Paris, covered Elle Germany with Heidi late last year.

Leni, on the other hand, has shot multiple Intimissimi lingerie campaigns alongside her mom.

While the kids are following in Heidi’s footsteps, Seal has been critical of the modeling industry.

“I don’t think that’s what he ultimately wants to do,” he told Page Six of his son last year, adding that modeling is “a stepping stone to getting what you want out of life. And it’s not necessarily a profession.”

But the kids say they always admired seeing their mom at work.

“I think watching my mom, as I grew up, watching her work, how happy she was, and how fun her job was… I was always really inspired by that,” Leni told Paper mag. “And when I’d go to set with her, I’d always try to get in the frame. I’d always steal her makeup artist. I’d tell him to do my hair, and I’d get in front of the camera, and I’d kind of crash the day. I just fell in love with it, and I’m still in love with it now.”

Henry added, “Yeah, same with me. We would always visit her on her set days. And we all were just super interested. She just looked like she was having fun in her sets. And I just wanted that feeling as well.”

Perhaps it could be a family business.
