The oldest of the three Kardashian sisters, Kourtney Kardashian gave birth to her first child, Mason Dash Disick, on Dec. 14, 2009. She shared this moment with the world in the final episode of the fourth season of the E! Entertainment hit reality series Keeping Up With the Kardashians. This episode delivered over 4.8 million total viewers, making it E!'s most watched telecast ever.

Kourtney's individual fame came in to play when she and younger sister Khloé Kardashian decided to break from the family and move to Miami to open up another DASH boutique. This was captured in their very own hit show on E!, Kourtney & Khloé Take Miami, which delivered through-the-roof numbers for the network. The series focused on the launch of the new boutique and the adventures they endured.

A highly business-savvy individual, Kourtney began her entrepreneurial career after graduating from the University of Arizona, when she and her mother opened "Smooch," a children's clothing store in Calabasas, Calif. Along with sister Khloé and Kim Kardashian, Kourtney continues to co-own and operate DASH boutiques in Los Angeles, Miami and New York.

Kourtney now has three childreen; Mason, Penelope Disick and Reign Disick, with her ex-boyfriend Scott Disick.
