Why Did Leni Klum Change Her Name?
Leni’s birth name is Leni Olumi Klum. When she was adopted by Seal in 2009, she legally took the surname Samuel (Seal’s last name is Henry Samuel).
However, when she began her modeling career, she chose to use her mother’s last name, Klum, for professional reasons. “Klum” is a globally recognized name in fashion, so this helped boost her visibility and brand.
So, she didn’t exactly “change” her name — she just uses “Klum” professionally while being legally known as Leni Samuel.

No, Seal is not Leni Klum’s biological father. Her biological father is Flavio Briatore, an Italian businessman.

Their relationship shows that family isn’t only about biology — love and commitment matter most.
