Personal life:Klum married stylist Ric Pipino in 1997; the couple divorced in 2002. Following the divorce, she dated Flavio Briatore. In the autumn of 2003, Klum announced she was pregnant by Briatore. The same day she made this announcement, Briatore was photographed kissing Fiona Swarovski, a jewelry heiress. Klum and Briatore split shortly thereafter.

Klum gave birth to her first child, Helene "Leni" Boshoven Klum on May 4, 2004 in New York City, New York. According to Klum, Briatore, Leni's biological father, is not involved in the child's life; she has stated emphatically that "Seal is Leni's father."

In early 2004, while still pregnant, Klum began a relationship with musician Seal. Klum and Seal married on May 10, 2005, on a beach in Mexico. They have three biological children together: sons Henry Gunther Ademola Dashtu Samuel (born September 15, 2005) and Johan Riley Fyodor Taiwo Samuel (born November 22, 2006) and daughter Lou Sulola Samuel (born October 9, 2009).

On hearing her family referred to as a "patchwork family," Klum said, "I'm not white, I'm a shade of brown," and added, "We're all different shades and we came together and we all love each other...it's actually kind of nice to have a 'patchwork family'."

In 2008, Klum became a naturalized American citizen.
On October 5, 2009, Klum filed a petition to change her name to Heidi Samuel.
