Happy birthday, Leni Klum!

The model celebrated her 21st birthday on Sunday, May 4, with a special tribute from her mom, Heidi Klum.

“Happy Birthday Leni. I love you with all my heart ❤️,” Heidi, 51, wrote in a touching Instagram post to her look-alike daughter.

Accompanying the message were two throwback photos of Heidi with Leni as a baby. One image showed the supermodel kissing her daughter’s forehead, and a second snapshot showed Heidi smiling in a hospital bed while cradling Leni as a crying newborn.

Heidi also posted a photo on her Instagram Stories of herself walking in New York City with baby Leni, who was strapped to her chest.

Heidi shares Leni, as well as her three other children — Henry, 19, Johan, 18, and Lou, 15 — with her ex-husband Seal.

The Project Runway star and the musician, 62, announced their separation in January 2012, and their divorce was finalized years later in October 2014.

Heidi’s four kids also spend time with her current husband, Tom Kaulitz, who considers himself an “extra dad” to them.

Leni, Henry, Johan and Lou even helped Kaulitz, 35, plan his surprise proposal to Heidi in 2019.

Heidi and Leni have a close mother-daughter relationship.

Back in October 2022, Leni spoke with PEOPLE about coming up in the same industry as her mom, and she addressed the “nepo baby” status attached with it.

“It’s just a fact. My parents are famous,” she said of carving her own path while being the daughter of celebrities.

“I did get help starting off, and I know that people would dream to start off with what I had. I’m so grateful that I’ve been able to take what was gifted to me by my mom,” Leni continued.

“But I am doing the work and putting in the time. Now I’m working on my own, traveling alone, going to school. My mom and I just have the same love for the same thing,” added the star.
