Heidi Klum (born June 1, 1973) is a German American model, television host, businesswoman, fashion designer, television producer, and occasional actress. In 2008, she became an American citizen while maintaining her native German citizenship.

In 1997, Klum married stylist Ric Pipino. The couple divorced in 2002.

Klum began a relationship with Flavio Briatore (the managing director of Renault's Formula One team) in 2003. The following year, Klum publicly announced her pregnancy. She gave birth to their first child, Helene Boshoven "Leni" Klum, in May, 2004 in New York City.

In early 2004, while still pregnant with Leni, Klum began a relationship with musicianSeal. With Briatore no longer involved in Heidi's life, Seal became Leni's de facto father. Seal was present for Leni's birth and Klum has stated emphatically that "Seal is Leni's father". Klum and Seal became engaged in December 2004 on a glacier in Whistler, British Columbia and married on May 10, 2005 on a beach in Mexico. They have three biological children together: sons Henry Gunther Ademola Dashtu Samuel (born 2005) and Johan Riley Fyodor Taiwo Samuel (born 2006), and daughter Lou Sulola Samuel (born 2009). On November 21, 2009, Klum officially adopted Seal's surname and became legally known as Heidi Samuel. Soon after, in December 2009, Seal officially adopted Leni, and her last name was changed to Samuel. During their marriage, Klum and Seal renewed their vows to one another each year on their anniversary in front of family and friends. On January 22, 2012, the couple announced that they were separating after almost seven years of marriage. She filed for divorce from Seal three months later on April 6, 2012. She also requested that her name be restored to her birth name of Heidi Klum.

Klum confirmed that she has been dating her bodyguard Martin Kristen since September 2012
