Heidi Klum shared rare throwback photographs of her and Seal’s daughter, Lou, as she celebrated her birthday. On Thursday, the model took to social media to congratulate her daughter on turning 16.

“Lou my beautiful sunshine ❤️ / Happy 16 th Birthday 🎁🥳🎈🌺🎂,” Klum wrote in the caption of an Instagram post. “I love you with my whole heart ❤️”

Heidi Klum’s daughter Lou celebrated a milestone birthday

Her post included several family photos and videos, including one in which we see Klum, Lou and her siblings Leni, Henry and Johan. They are seen posing in front of a brick wall and at the beach. In the carousel, one video shows Lou celebrating her fifth birthday.

Lou is Klum and Seal’s youngest child. The model has three other children, 21-year-old Leni Klum, 20-year-old Henry Samuel and 18-year-old Johan Samuel, according to E! News.

Klum has shared family moments with the public in the past. Last month, Klum celebrated her inaugural HeidiFest in Germany, where she was joined by her family to celebrate Bavarian culture. 

“Those are my roots — even if I’m not from Bavaria, I’m still German,” she told OK! Magazine. “I grew up here, too, and in that respect, I think it’s nice for my children to see a bit of my roots, too.”

She was joined by her four children at the event. Her husband Tom Kaulitz, brother-in-law Bill Kaulitz and mother Erna Klum were also present.

Heidi Klum says her daughter Lou loves Halloween as much as she does

October is an important month for Klum and her fans, as she is known for her yearly Halloween party and show-stopping costumes. Yet, she dedicates a particular passion to the celebration to her daughter Lou, whom she said loves to dress up.

“Lou, especially. She makes her own things,” Klum told People in 2024. “She’s also really into anime. She makes all the wigs herself.”

“She’s pretty talented, I have to say, more talented than me when it comes to building things,” she added. “If anyone has the major block about dressing up and that stuff, it would be my Lou.”
