Heidi Klum's Daughter 'Too Scared' To Smile In Sheer Braless Dress

Heidi Klum's daughter, Leni Klum, is getting asked if she's okay as fans react to a new photo of her. Earlier this month, a dedicated Instagram account reposted footage of the 21-year-old as she stunned in a see-through, embellished dress. Putting her killer curves on display, Leni dropped jaws in a plunging, skintight black dress, looking glamorous for a night out in the wake of her Venice Film Festival appearances. The rising sensation, who recently posed in unbuttoned pajamas for an Instagram photo promoting Intimissi, sizzled in her tight strappy look, but for one fan, she was looking "scared." The fan even asked if Leni was too afraid to "smile" as they appeared to pity her.

Scroll for the video. Keeping her expression neutral as she showed up to another event, Leni reminded the cameras of the figure she's inherited from 52-year-old supermodel mom Heidi.

Slipping her braless curves into a figure-hugging, long dress that was largely see-through, the Dior Beauty ambassador stunned with a cleavage flash, looking classy and elegant while teasing her abs and killer hips.

Dolling herself up with plenty of matte makeup, including blush worn over blended foundation, Leni dazzled with her hair worn down, sporting a sleek finish as she highlighted her defined brows and plump pout. The Instagram favorite also wore strappy black heels as her dress fell just above the ankles.

"Smile? You Look scared to ??? Xo sending HUGS," one concerned fan wrote. Leni tends not to spark concern, though. In a recent share, she was actually criticized for stripping down with mom Heidi, adding to the pile of weirded-out fans who still aren't keen on the duo fronting luxury lingerie brand Intimissi.

At the end of August, Heidi Klum's daughter lounged around her Venice hotel suite bed with her mom, and fans got the ick with her going braless and unbuttoned. "Goodnight Venice … @intimissimi," Leni wrote while flashing hints of her bare chest. Meanwhile, German-born Heidi slipped her Amazonian physique into a cream satin two-piece for a comfy, luxurious nightwear look.

"Attachment disorder !? Is it just me that most of the time Leni doesn't feel like posing with her mother?" one fan remarked. "A lot of love and power for leni to free herself from the captivity of her mother," the user added.

Another fan, also frowning on the promo, replied: "Weird & inappropriate. Why are they trying to normalise this stuff."

Heidi Klum's daughter was just 18 when she began posing in undies with her mother for Intimissi. Heidi has noted the backlash resulting from the campaigns, but she's always defended her ambassador role with Initimissi coming as a joint deal with Leni.
