Kourtney Kardashian is the oldest child of Kris Jenner (wife of Olympic decathlete Bruce Jenner) and late O.J. Simpson defense attorney Robert Kardashian. She is also the doting mother of adorable 1-year-old "googootante" Mason Dash Disick. The baby daddy is Kourtney's on-and-off boyfriend Scott Disick, a volatile Long Islander prone to excessive drinking and bad behavior. The couple's shenanigans are a frequent theme of the Kardashians' reality shows, and Scott's drunken antics have not made him a fan fave. At the end of the last season of Keeping Up with the Kardashians, they began trying for a second child. Rumors have been swirling ever since that Kourt is preggers and she and Scott are going to elope, but none has been confirmed.

A seasoned entrepreneur, Kourtney has opened children's clothing boutiques in both L.A. and New York with her mother Kris. She also co-owns and operates DASH, a fashion boutique with locations in L.A., Miami, and New York City, with her sisters Kim and Khloé. (DASH is an authorized retailer of the very popular Junk Food T-shirts.) She and her sisters released a line of clothing for Bebe in the Spring of 2010; another clothing line, K-Dash, which is being sold on QVC; and an Armenian-inspired jewelry line for Virgins, Angels, and Saints. If you want the inside scoop on her sprawling family and rise to fame, pick up a copy of Kardashian Konfidential, the sisters' joint memoir.

Still haven't had enough Kourtney? You needn't venture much further than Sephora, where you can pick up her sunless tanner, Kardashian Glamour Tan.

Kourtney and her sister Kim, who often butt heads over Kourtney's tempestuous romance with Scott, have brought their act to the Big Apple in Kourtney & Kim Take New York, the Kardashians' latest reality spin-off.
