Klum appeared on the cover of the Sports Illustrated Swimsuit Issue in 1998 and hosted the Victoria's Secret Fashion Show across the 2000s. As host and judge of Project Runway from 2004, she shared the 2013 Emmy for Outstanding Host with co-host Tim Gunn, and has hosted Germany's Next Topmodel since 2006.
Beyond the screen she built her own lines: a clothing collection for Jordache, the HKNB active line with New Balance launched on Amazon, Heidi Klum Intimates lingerie, maternity lines, and two namesake fragrances. In 2009 she became Barbie's official ambassador for the doll's 50th anniversary.
