Heidi Klum, 51, and Daughter Leni, 20, Under Fire for 'Inappropriate' Racy Photos

Heidi Klum may have taken things a step too far during her latest ad campaign, in which she and her daughter Leni , 20, posed alongside each other in lingerie for the brand Intimissimi.

The 50-year-old wore a matching maroon set for the occasion, while the younger model was clad in black floral lace in a new photo shared by the Italian luxury brand , which described the new "empowering, stylish collection" as being a combination of "family, fashion, [and] femininity."

Leni also shared a few slides from their photoshoot on social media, leaving many feeling unsettled by the intimate imagery.

"Quite strange to do this with your mum," one comment read, with another stating, "This is kinda weird."

"This genuinely feels wrong … stop shooting lingerie with your mom!!!" a third person wrote, adding that it was "Creepy."

Under another post from the brand , which showed Klum and her daughter joyfully filming one another with a vintage camera, someone else agreed that that the whole thing was "really weird and inappropriate."

"Mother and daughter filming eachother [sic] in lingerie?!!!" they questioned. "What is this????😳😳😳😳."

However, plenty of people came to the pair's defense, too, with one writing, "Two beautiful ladies! I can't imagine why anyone would be critical of this. People have been modeling underwear forever. ❤️🌻."

It's not the first time the two have modeled together for the brand , but the intimate video, which seemed to many like it was filmed between partners rather than a parent and child, was "incredibly disturbing" for fans in comparison.
