<P> The reality series revolves around the children of Kris Jenner, and originally focused mainly on the children from her first marriage to deceased attorney Robert Kardashian: Kourtney, Kim, Khloé, and Rob . Kris' children Kendall and Kylie from her subsequent marriage to American athlete Bruce (later Caitlyn) Jenner have also been featured on the show since its beginning, along with Jenner's son Brody from another marriage, although he appeared very few times during the early seasons, mostly being called by his step - brother Rob to babysit their half - sisters Kylie and Kendall . Kourtney's boyfriend Scott Disick has also been appearing frequently on the show since the first season, as well as on the show's spin - offs . Cast members also include numerous friends and other acquaintances of the family members, most notably Malika Haqq and Jonathan Cheban who joined Keeping Up with the Kardashians in the second and third seasons, respectively . </P> <P> Most of the Kardashian sisters' significant others have appeared on the reality series . Kim's relationship with football player Reggie Bush was featured on the show when they were dating; after the breakup, Bush commented on appearing on the show saying that he never felt comfortable being followed by cameras, adding: "I do it because it's important to (Kim)." Rob's relationship with singer Adrienne Bailon has also been documented on the show when they were dating from 2007 to 2009; although Bailon later admitted that the decision to appear on the show, and be associated with the family, hurt her career . Kim's ex-husband Kris Humphries first appeared on the show during the premiere of the sixth season; their relationship was chronicled throughout the season and ended with the couple's wedding special "Kim's Fairytale Wedding: A Kardashian Event". They eventually went through a highly publicized divorce; Kardashian's former publicist later claimed that Humphries was allegedly set up to be portrayed on the show in a negative way and that the short - lived marriage was staged for the cameras as a ploy to generate money . </P> <P> Khloé married basketball player Lamar Odom during a fourth - season premiere aired in 2009 . He later had a major role as part of the supporting cast of the series, though he did not appear regularly during the following seasons as he was attempting to repair his marriage with Khloé . Kim's current husband Kanye West made his first appearance on Keeping Up with the Kardashians in July 2012 during the seventh season when he started dating Kim . However, West was seldom seen in subsequent seasons . He explained the reasons for not appearing on the show later: "You know, the amount of backlash I got from it is when I decided to not be on the show anymore . And it's not that I have an issue with the show; I just have an issue with the amount of backlash that I get ." He also criticized the show for its cinematography and further complained about the way how the show is filmed . In the eighth season, Caitlyn Jenner's sons Brandon and Brody Jenner, as well as Brandon's wife Leah, joined the cast for regular appearances . </P> <P> The success of the reality series resulted in the development of several spin - off shows and other related programming . In April 2009, E! announced the first spin - off of Keeping Up with the Kardashians entitled Kourtney and Khloé in Miami, which was later renamed Kourtney and Khloé Take Miami . The series followed the sisters who moved to Miami to open a new Dash boutique . Ted Harbert, president and CEO of Comcast Entertainment Group, considered the sisters capable of handling their own standalone series . "It's a very simple formula that we took from scripted TV and applied to a reality show . (...) There are a lot of family sitcom elements to' Kardashians,' and we think that humor and warmth will carry over to Miami," Harbert added . The show premiered on August 16, 2009 to very high ratings; the first episode brought in 2.7 million total viewers and then became the most - watched show on the network since The Anna Nicole Show in 2002 . The spin - off was subsequently renewed for a second season which premiered on June 13, 2010, and later returned as Kourtney and Kim Take Miami for a third season on January 20, 2013 . Additionally, a series of webisodes entitled Lord Disick: Lifestyles of a Lord were released following the show, which showcased Disick as he informed viewers how to live like a "king". </P>
