Leni Klum in a see-through dress playfully kisses her supermodel mom Heidi

Leni Klum looked sensational in a see-through dress while getting cosy with her supermodel mum Heidi Klum to promote their latest lingerie campaign.

The stars posed for an air kiss on the lips while posing up a storm for Intimissimi – and nearly broke the internet while doing so.

For her part, 18-year-old Leni donned a floor-length sheer black dress, letting her own lacy bra and knickers show through the transparent fabric.

A pair of knee-high leather boots finished off her daring ensemble, featuring a stiletto heel to add a few extra inches to her height.

Leni’s bra was embellished with spidery floral designs under her high-necked gown, and the star let her honey blonde hair fall in loose waves around her shoulder as she grinned for the camera.

For make-up, she opted for a glossy pink lip and pale shadow around her eyelids, adding volume to her lashes with dark mascara.

Mum Heidi, meanwhile, donned a thigh-skimming hot pink gown with sheer cut-out sections and a high turtleneck.

Exposing her slender legs, Heidi donned a pair of glittery pink sandals with a heel to rival her daughter’s, with her bright red pedicure on display.

Mother and daughter looked almost identical with Heidi’s highlighted tresses worn loose, only a full fringe to separate the pair’s look. She even matched up her daughter’s make-up style with a matching pink pout.

Captioning the cheeky video on Instagram, Heidi tagged Intimissimi and wrote: “We love you!” with a heart emoji.

The pair have come under fire for posing for the lingerie brand in the past, with one photoshoot showing them donning matching undies causing a stir online.
