A member of the Jenner-Kardashian family, Kourtney became known as a result of the hit E! reality show starring her blended family -- including sister Kim -- Keeping Up With the Kardashians, in 2007.
Kourtney and her younger sister sister Khloe became the subjects of their own E! reality spin-off, Kourtney and Khloe Take Miami, in August 2009 when they opened a new location of their Calabasas, Calif.-based clothing store, Dash, in Miami. Kourtney and her mother, Kris Jenner, also own a children's boutique called Smooch.
Kourtney has been in a long-term on-again, off-again relationship with entrepreneur Scott Disick. The couple got engaged in 2007, but split in February in 2009 after she suspected him of cheating. The pair reunited after discovering she was pregnant with Disick's child, whom she gave birth to in December 2009 and named Mason Dash Disick. In July 2012, the pair welcomed daughter Penelope Scotland.
