Heidi Klum and daughter Leni have sparked an online debate after posing together in lingerie.

Klum, 51, and Leni, 20, stand side by side in an ad for Intimissimi shared on Instagram Monday.

The America’s Got Talent judge wore a maroon bra and lingerie set while Leni posed in a black outfit.

Opinions were mixed, with some sharing that they felt uncomfortable with the scene of mother and daughter posing in lingerie.

“This makes me feel uncomfortable,” one user wrote.

“Heidi looks great. But why are you posing in revealing lace lingerie with your mom?” another added. “Gives me a bad vibe. And before anyone tells me to unfollow. Don’t! I didn’t follow it in the first place. It popped up on my feed. I don’t have anywhere on this ad to block it anyway so I’m commenting.”

“Dude, that’s your mom,” someone shared.

However, not everyone has problems with images.

“Two beautiful ladies! I can’t imagine why anyone would criticize this. People have been modeling lingerie for a long time,” wrote one user.

“I’m not bothered by this photo,” another added. “There’s nothing disturbing going on here. The underwear isn’t sexual. I don’t see what the problem is.”

Klum’s representative did not immediately respond to Fox News Digital’s request for comment.

Leni began her modeling career at the age of 16. Klum and her daughter appeared together on the cover of Vogue Germany’s January/February 2021 issue.

“So excited for my first cover!! Had so much fun on set with @voguegermany couldn’t have dreamed of a better start!! Thank you for being by my side @heidiklum,” Leni wrote on Instagram at the time.

Klum gave Leni advice in a 2023 interview with Fox News Digital.

“I think the best advice I could give my daughter about modeling is to always be happy with yourself when you look in the mirror. I think that’s the most important thing,” Klum said on the “America’s Got Talent” red carpet.

“Don’t try to please anyone,” Klum suggests. “I think it’s important to say no… because I feel like… generally, we want to please and… say ‘yes’ more than ‘no.’ But I want her to know that if there’s something you don’t want to do, you can just say no.”

This isn’t the first time Heidi and Leni have posed together for the Italian lingerie brand. Intimissimi posted a photo of the two posing together in bras and underwear in October 2022. That ad campaign also received mixed reviews online.

“It’s weird to be pornographic towards your daughter right when they’re legal,” one person wrote on the post.

“Very worrying,” one user added.

Another user said: “I like to think I’m progressive on these things but mother and daughter wearing lingerie in the same video shoot is a bit off-putting.”

Others praised the initial campaign.

“Mother and daughter are amazing,” one person wrote.

One user added: “Wow, finally a mom modeling with her daughter instead of the influencers I’m sick of seeing all the time.” “This ad is good.”
