Heidi Klum beamed with pride as her lookalike daughter Leni walked the runway for Dolce & Gabbana.
The 18-year-old looked incredible as she joined her fellow models on the catwalk for the fashion show in Sicily on Saturday evening.
Supporting her daughter on the night, Heidi, 49, shared a series of photos as she documented Leni's special moment for the fashion brand.
In one, the mother and daughter posed together as the former supermodel joined her daughter backstage.
Heidi cosied up to Leni in a semi sheer jumpsuit with colourful jewels, while the young model was dressed in a black corseted outfit from D&G.
"Good Luck my Baby," Heidi captioned the sweet photo.
The mum-of-four also shared a video as Leni took to the catwalk, followed by a playful snap of herself posing with the fashion brand's iconic designs.
Following the event, Heidi uploaded a snap with her daughter as they affectionately hugged each other.
Heidi attended the star-studded fashion show alongside Helen Mirren, Mariah Carey, Sharon Stone, and Lupita Nyong'o.
The extravagant affair took place at the Cathedral of Syracuse in Siracusa, Sicily.
The former model welcomed daughter Leni with Italian businessman Flavio Briatore, 72, but she was raised by Heidi's ex-husband Seal, 59.
Heidi and Seal - who split in 2014 - also share Lou, 12, Henry, 16, and Johan, 14, together.
Last year, the proud mother shared her concerns for daughter Leni's modelling career , admitting she thought she was "too young" to be in the spotlight.
She told People magazine: "I always thought she was too young. We always also decided to keep the children out of the public eye.
"But she's driving a car now, she's 16, so I figured if you can do that, you can also model now if this is what you wish to do."
Despite her initial concerns, Heidi is adamant her daughter has what it takes to be successful.
The star continued: "Obviously, as a mother, [I want my] child to do what she wants to do. The industry is great and I love it and I've been in it for over 20 years but it's also, it's a lot of traveling, it's different.
"You have to be a strong person, especially as a woman you have to be very strong."
It comes after Heidi recently modelled alongside Kim Kardashian for her shape wear collection, SKIMS.
She also joined Tyra Banks, Candice Swanepoel and Alessandra Ambrosio on the shoot.
