Heidi Klum's Daughter Highlights '12 Out Of 10' Body In String Bikini

Heidi Klum's daughter, Leni Klum, is back on Instagram as she shows off her swimsuit curves. The 21-year-old made it very clear that she was missing summer in her Monday share, one likely coming as a throwback from warmer months. Displaying her teeny shoulders and ample curves in a black bikini, Leni stunned in shades from a beach, keeping her Hot Girl Summer alive and even seeing mom Heidi agree. Leni, who jointly fronts lingerie brand Intimissimi with her 52-year-old mother, quickly gained a comment from the supermodel.

Scroll for the snap. Lying back for a close-up snap, Leni displayed her slender arms and shoulders, also drawing the eye to her ample cleavage.

Sticking to a classic shade of black, the Dior Beauty ambassador wowed in a plunging halterneck swimsuit, highlighting her figure while going makeup-free as she glammed up in dark shades.

Enjoying a quiet, shaded spot while lying on a cream-colored lounger, Leni lowered her shades just enough to show off one of her light eyes, also rocking a flawless brow as she showed off her natural beauty. The rising sensation wore her dark hair down and damp, completing her look with a chic pink manicure. "Missing summer," she wrote.

Agreeing, mom Heidi gained likes for saying: "Me too" while throwing in summer-themed emoji that included a sunshine and swimsuit. "My beauty," another fan wrote. Leni's figure has previously been referred to as a "12 out of 10" by fans, per The Blast.

Heidi Klum's daughter turned heads with her curves last year, and it was double trouble as she joined mom Heidi while in Cannes. Enjoying some downtime between Cannes Film Festival appearances in 2024, Leni sizzled in a blue string bikini with red piping, going itty-bitty as Heidi contrasted her daughter in a bandeau, floral two-piece.

"Would never have guessed they were mother and daughter; they look nothing alike," one Daily Mail user replied. Frowning on the photos, another said: "It seems sad that a mother would behave and also encourage their daughter to behave in this way. Mom is likely struggling with aging, so here we go."

When fans reacted to this shot on Instagram, the replies were mostly positive. One user loved that the images appeared "unedited," saying that they were "great!"

Heidi Klum's daughter has since made headlines for joining her mother at the 2025 Venice Film Festival, alongside continuing to promote luxury lingerie line Intimissimi with her mom. She is followed by 1.8 million on Instagram. Follow us on Facebook for more updates from Heidi and Leni!
