Kim Kardashian has always made it to the headlines, whether for her infamous sex tape with her former boyfriend Ray J or her recent marriage to Kris Humphries.

However, her sister Kourtney, who rose to fame with Keeping Up with the Kardashians, an American television reality show, has not always been seen in the same light.

Kourtney is the eldest child of Kris Jenner and defense attorney Robert Kardashian and the sister of socialites Khloé Kardashian Odom, Kimberly Kim Kardashian Humphries and Rob Kardashian.

Has Kim Kardashian, who is now Kim Kardasian Humphries, stolen the limelight from the start and have we missed out on the elder sister?

Here are pictures of the sisters.
