People Editorial Guidelines Updated on May 23, 2024 05:26PM EDT Heidi Klum and Leni Olumi Klum had a sweet mother-daughter moment on the Cannes amfAR Gala red carpet. On Thursday, May 23, the model, 50, attended the event alongside her 20-year-old daughter Leni. The event, which raises money for AIDS research, is one of the most glamorous events during the film festival. The mother-daughter duo posed for photos in dramatically different ensembles. Heidi wore a ruffled pink tulle Lever Couture gown with an asymmetric silhouette and long train. She accessorized with matching pumps and large silver and green earrings. Leni, on the other hand, opted for a sheer black knit dress with 3D floral details around the bust and hips. Her long dark hair was swept into a half-up style, and she added a gemstone choker for some bling. Heidi Klum and Leni Olumi Klum.
