Kourtney Kardashian Through The Years

Kourtney Kardashian Through The Years — Kourtney Kardashian, born April 18, 1979, may have started as the more quiet Kardashian sister but has since become a force to be reckoned with. Over the years, Kourtney has grown from a mere reality star into a cultural icon, fashionista, and mother-of-three.

The eldest Kardashian sister rose to prominence along with her family in 2007, with the premiere of ‘Keeping Up With The Kardashians’. From there, the projects multiplied, with spin-offs like including ‘Kourtney and Khloé Take Miami’ and ‘Kourtney and Kim Take New York’. She enjoyed clothing collaborations with brands like Bebe and PrettyLittleThing. In Mar. 2019, she founded the lifestyle site Poosh.

Through it all, Kourtney’s main focus has been motherhood and family. The star shares three children, Mason, Penelope, and Reign, with ex Scott Disick. She has been engaged to rocker Travis Barker since Oct. 2021.
