Leni Olumi Klum was born on May 4, 2004, in New York City. She is a German-American fashion model and the eldest daughter of supermodel Heidi Klum.
At 16, she made her professional debut on the cover of Vogue Germany alongside her mother, launching one of the most high-profile modeling introductions of recent years.
She is signed with IMG Models and has since worked with Dior Beauty, Fila, Intimissimi, and About You, building her own career beyond her family name.
Who is Leni Klum?
Leni Olumi Klum is a fashion model based in New York City. She is the eldest child of Heidi Klum and Italian businessman Flavio Briatore, and the adopted daughter of British singer Seal.
She first came to public attention through her modeling debut at the end of 2020. Since then, Leni has worked on editorial campaigns, runway shows, and brand partnerships, establishing a career separate from her mother’s considerable shadow.
Her modeling agency is IMG, one of the world’s leading talent management companies in fashion. The same agency represents many of the industry’s top names, which places Leni in a serious professional environment from the start of her career.
Leni also holds dual citizenship in Germany and the United States. She acquired American citizenship in 2020. Both her German heritage through her mother and her Italian roots through her biological father are visible in her appearance and public identity.
Early Life of Leni Klum
Leni grew up in Los Angeles with her mother Heidi, her adoptive father Seal, and her three younger half-siblings: Henry, Johan, and Lou. Heidi and Seal married in 2005 and separated in 2012, with Leni growing up during the years they were together as a family.
Her biological father, Flavio Briatore, was not involved in her upbringing. He and Heidi briefly dated in 2003 and 2004 before separating while Heidi was pregnant. Seal was present at Leni’s birth in 2004 and officially adopted her in 2009. Leni has said publicly that she considers Seal her dad.
Heidi Klum protected Leni from the spotlight during her childhood. Leni has spoken about wanting to model from around age 11 or 12, but her mother did not allow her to start professionally until she turned 16.
When the clothing brand Brandy Melville reportedly approached Leni about a modeling project when she was 12, Heidi declined. Leni later acknowledged and appreciated that decision.
After her parents’ separation, Heidi married Tokio Hotel guitarist Tom Kaulitz in 2019. Leni has described her relationship with Kaulitz as supportive.
In 2023, Leni reestablished a relationship with her biological father Flavio Briatore. She also has a half-brother through Briatore’s marriage to model Elisabetta Gregoraci, whose son Nathan Falco was born in 2010.
Leni Klum Age
Leni Klum is 22 years old as of 2026, born on May 4, 2004. Her zodiac sign is Taurus. She made her professional modeling debut during that same year she turned 16, appearing on the cover of Vogue Germany in December 2020.
Leni Klum Ethnicity and Nationality
Leni holds both German and American nationality, acquiring U.S. citizenship in 2020. Her ethnic background combines German on her mother’s side and Italian on her biological father’s side.
This mixed European heritage is part of the public narrative around her identity in the fashion world, where she has been described as reflecting the looks of both her parents.
Leni Klum Height and Weight

Leni attended Pacifica Christian High School in Los Angeles and graduated in 2022. After graduating, she moved from Los Angeles to New York City to study interior design at college while also pursuing her modeling career.

Leni Klum Career

Modeling Debut and Early Work (2020-2021)
Leni’s formal debut came in December 2020 when she appeared on the cover of Vogue Germany’s January/February 2021 issue alongside her mother.
The two wore colorful matching pantsuits in a shoot that announced Leni’s entry into the professional fashion world. Heidi celebrated the occasion publicly on Instagram, marking it as a milestone moment for both of them.
Shortly after, in January 2021, Leni walked the runway at Berlin Fashion Week. She opened a digital runway show, presenting outfits from designers including Lala Berlin and Kaviar Gauche. The appearance confirmed she was building a real career rather than trading on a single high-profile debut.
That year, Leni also began booking editorial work with major publications. She appeared in magazines including Hunger and Harper’s Bazaar Kazakhstan in addition to continued German press. By this point, she had already begun working with Dior Beauty and Fila as brand partners.
Intimissimi Campaign and Growing Profile (2022-2023)
In 2022, Leni and her mother Heidi starred together in a campaign for the Italian lingerie brand Intimissimi. The mother-daughter shoot attracted significant attention online and became one of Leni’s most widely discussed modeling jobs. Though it drew some criticism, the campaign raised her public profile considerably.
Also in 2022, Leni served as a guest judge during the semi-final of Germany’s Next Topmodel on ProSieben, the show her mother hosts. She returned the following year, appearing in the season 18 finals of the same show in 2023.
Leni’s editorial output grew through 2023. She appeared on the cover of Flaunt magazine in March 2023. She also appeared in Zoo Magazine and L’Officiel Monaco through 2024, steadily adding publications to her portfolio.
In September 2022, she and boyfriend Aris Rachevsky made their public debut as a couple at Milan Fashion Week, attending the About You show together.
Brand Campaigns and Recent Work (2024-2026)
Leni’s brand work continued to expand in 2024 and 2025. She appeared in Zoo Magazine’s summer 2024 editorial and cover alongside a Dior-themed shoot.
She also returned to Intimissimi for a Fall 2025 campaign, extending her association with the Italian brand beyond the 2022 debut she shared with her mother.
In March 2025, she covered Glamour Germany, photographed by Agata Serge. That same period saw her appear in L’Officiel Monaco’s December 2024 covers, shot by George Livieratos. She has continued to build a consistent editorial presence across European and international fashion publications.
Leni moved from Los Angeles to New York City after high school, both to attend college and to position herself in one of the world’s fashion centers. The move underscores her dual commitment to education and a long-term modeling career.
