AceShowbiz - Heidi Klum, 51, and Leni Klum, 20, posed in various sets of lingerie, smiling and laughing for photos promoting the brand's Fall-Winter collection. They also filmed a video where they used an old camera to record each other showing off their curves in the lingerie.

Intimissimi captioned the video, "Lace that flatters, support that empowers - From generation to generation, #intimissimi celebrates every facet of femininity." However, the campaign has been met with mixed reactions on social media, with some users calling it "strange" and "inappropriate."

"Am I the only one thinking this is a bit weird? This campaign at least doesn't work for me. Like who dresses up in lingerie with his mom and prances around taking pics? I don't know... I mean nothing wrong with that but it's like not something that makes sense in an ad, when I am looking to buy lingerie and stuff..." one person commented. "This is so strange ? What kind of advert is this ??? Another user commented.

Others defended Heidi and Leni, arguing that they were simply showing their close relationship by working together. "They are just modeling. They are not making out. Mother and daughter modeling for the same brand," one person wrote.

"BEAUTIFUL and I don't understand the comments who say it is weird to do this with your mom. WHY? Do they eventually see the female body and lingerie as something always sexual? Or what is the problem? I'm really curious to understand their way of thinking, because to me, this is just a mother & daughter who are like best friends LOVE IT!" a fan gushed.

Heidi has been previously criticized for posing in lingerie with Leni in an earlier Intimissimi campaign, and for including her 80-year-old mother Erna in the mix. However, she has also received support from fans who appreciate the mother-daughter bond they share.
