Heidi Klum’s children are officially stepping out of their mother's shadow, and the latest updates as of December 15, 2025, confirm that a new generation of the Klum-Samuel dynasty is taking over the fashion and entertainment world. For years, the supermodel has kept her four children—Leni, Henry, Johan, and Lou—relatively private, but with the eldest now in her twenties and the others quickly becoming young adults, their high-profile careers and public appearances are becoming major news.

From a surprise runway debut at Paris Fashion Week to a burgeoning modeling career that rivals her mother's, the Klum-Samuel kids are making their own headlines. This deep dive reveals the full biography of each child, their current age, and the most recent, unique career moves that have captivated fans globally.

Complete Biography: Leni, Henry, Johan, and Lou Samuel

Heidi Klum is a mother of four, sharing her three youngest children with ex-husband, the musician Seal. Her eldest daughter, Leni, was born during Klum's relationship with Italian businessman Flavio Briatore, but she was later adopted by Seal, whom Klum credits as Leni's true father. The entire family, including Klum's current husband, Tom Kaulitz, maintains a close and blended dynamic.

The Next Generation Takes the Runway: Henry Samuel's Shocking Debut

While Leni Klum's modeling career has been highly publicized, the biggest recent surprise from the Klum-Samuel children came in early 2025 with the unexpected runway debut of her younger brother, Henry Samuel.

Henry Günther Ademola Dashtu Samuel, who has always maintained a lower public profile than his sister, walked the runway for the Lena Erziak Haute Couture Spring/Summer 2025 show.

This high-profile event was part of Paris Fashion Week and immediately positioned Henry as a serious new face in the industry. The 20-year-old’s appearance drew strong reactions, with many noting his striking resemblance to his father, Seal, and his immediate comfort on the catwalk.

This monumental step into the world of high fashion by a second child of Heidi Klum and Seal has solidified the family's status as a true fashion dynasty. Henry also made a rare public appearance alongside his mother at the 2025 American Music Awards (AMAs), stepping in as Klum's last-minute date.

Leni Klum’s Evolving Modeling Career and Personal Style

Leni Klum, the eldest, continues to be the most visible of the siblings, having launched her career at the age of 16 with a joint cover for Vogue Germany alongside her mother.

Since then, Leni has built an impressive resume that includes campaigns for major beauty brands, solo magazine covers, and walking in international fashion shows. Her mother, a long-time judge on shows like Germany's Next Topmodel, has been a strong supporter of Leni's professional journey, emphasizing that she waited until Leni was 16 to allow her to pursue modeling.

Leni's personal style and willingness to embrace creativity were on full display at the annual Heidi Klum Halloween Party in 2025.

While Heidi Klum is known for her elaborate, transformative costumes, Leni turned heads by dressing as Camilla Cream, the main character from the children's book 'A Bad Case of Stripes,' which required her entire body to be painted.

This artistic choice highlights Leni's commitment to performance and character, distinguishing her from other 'nepo babies' in the industry and demonstrating her own unique flair. She continues to attend university in New York, balancing her studies with her demanding career.

The Younger Samuels: Johan's Artistic Path and Lou's Growing Privacy

While Leni and Henry have embraced the public spotlight, the two youngest children, Johan and Lou Samuel, maintain a more private existence, though recent milestones have brought them into focus.

Johan Riley Fyodor Taiwo Samuel: The Artistic Spirit

Johan, now 19, is known for his artistic and creative inclinations. His full name, Johan Riley Fyodor Taiwo Samuel, is one of the more unique in Hollywood, reflecting the diverse heritage and tastes of his parents.

Heidi and Seal have been seen reuniting for their children's milestone moments, including Johan’s graduation, suggesting a united front in co-parenting despite their 2014 divorce.

Johan’s interests appear to lean away from the high-fashion runway, focusing instead on creative pursuits, which is a common path for children of artists and musicians.

Lou Sulola Samuel: The Next Klum-Samuel Star?

Lou Sulola Samuel, the youngest, is now 16 years old. She is the last of the Klum-Samuel children to reach an age where a public career is a possibility.

Lou, like her siblings, has a powerful and meaningful full name. While she is still largely kept out of the media, the family has made rare, full-family appearances, such as a September 2025 outing at an event in Germany.

The family’s blended arrangement, which includes her stepfather Tom Kaulitz and her father Seal, has been a model of modern co-parenting. Klum and Seal have navigated the challenges of divorce and custody to ensure their four children are raised in a supportive environment, often reuniting for holidays and major life events.

As Lou enters her mid-teens, industry speculation is high about whether she will follow her mother and older siblings into the world of modeling, or if she will forge a different path, perhaps in music like her father, Seal, or stepfather, Tom Kaulitz (of the band Tokio Hotel).
