Heidi Klum & Daughter Leni Klum, 18, Twin In Lingerie Shoot

Model Heidi Klum and her 18-year-old daughter, Leni Klum, are twinning in a new lingerie shoot for Italian lingerie brand Intimissimi.

The 49-year-old Sports Illustrated Swimsuit cover model posted a few snaps to her Instagram page that shows her posing beside her daughter in lacy garments.

On Monday morning, the first-ever German Victoria's Secret model took to Instagram to share a few photos of her Intimissimi ad that features her and her daughter, Leni, standing side by side in lacy lingerie.

"Together with @intimissimiofficial we celebrate women; the love and support between a mother and her daughter; and how confident, beautiful and happy lingerie can make you feel," she wrote in the caption. "Check out our favorite styles online and in all Intimissimi stores and explore 'the art of Italian lingerie'."

She also repeated the ad in German, writing, "Gemeinsam mit @intimissimiofficial feiern wir Frauen, die Liebe und das Band zwischen Mutter und Tochter. Wir feiern, wie selbstbewusst, schön und glücklich man sich in Dessous fühlen kann. Unsere Lieblingsmodelle sind ab jetzt online und in allen Intimissimi-Geschäften verfügbar. Entdeckt 'die Kunst der italienischen Lingerie'."

Shortly after, Leni took to Instagram to share a snap of her posing beside her mother, writing, "@heidiklum and I for @intimissimiofficial !! You will love their Lingerie as much as we do!"

Leni also shared a video ad on Instagram that featured them both singing, dancing, and blowing kisses to the camera as opera music played in the background.

Leni repeated her mother’s caption in her own post. Although the “America’s Got Talent” judge doesn’t allow comments on her Instagram posts, the college freshman had no problems allowing her fans and famous friends to comment on the post.

One of the first people to comment was the brand itself, dropping three red heart emojis on the video. German author and influencer Riccardo Simonetti commented, “You both look stunning.” Another follower wrote, “You both seem very happy 👏👏❤️.” Another fan added, “❤️❤️ mother daughter.”

However, some fans felt that the ad was more awkward than the two let on. “Imagine shooting a lingerie commercial with your mom 😬,” one user commented. “👎🏽 nope,” another user wrote. “Really weird. Mother and daughter dancing around in lingerie. Really weird. I love these women but this campaign doesn’t make me want to buy. It’s off-putting. Who dances half-naked with their mom?” another user chimed in.

Although Leni is still following in her mother's footsteps as a model, she is also studying fashion in New York City and just started college in August after graduating from the Pacifica Christian High School in Santa Monica in June.

Leni's modeling career first began when she appeared beside her mother on the cover of German Vogue in 2020. Leni made her runway debut eight months later when she appeared in Dolce & Gabbana’s 2021 Alta Mode show in Italy and has walked the runway in several other fashion shows since then.

In an August 2022 interview with ET, the proud mom-of-four couldn’t help but gush over her eldest daughter going off to college. “I am [so proud]. You know, she has her head screwed on right,” she said. “Right now, college is on top of the list. It’s not modeling and she’s really excited for that next chapter in her life.”

“Unfortunately, she is moving away from home,” Heidi admitted. “Which is obviously sad but at the same time that she’s got enough to go for it. She’s moving to New York. I started in New York, so she knows New York inside and out because we shot ‘Project Runway’ there for so many years. So, she knows it well because I always move my family to New York when we were still filming. So, I think she’s going to have a good time, but my heart will be sad.”

Heidi, who started her own career in New York City, reflected on the "positive and negative sides" of her daughter pursuing a modeling career.

“I think any industry has positive and negative sides," she said. "In this industry, we see traveling. If you travel too much, it’s hard to travel on your own a lot.”

Fortunately, it looks like Leni won't have to be alone with support from her mother and her famous friends. In another photo shoot earlier this month, Leni stepped out without any pants on in a new ad for @superga that fans can check out by clicking here.
