Kris Jenner is reportedly developing a new spin-off show about her grandchildren called "Keeping Up with the Kids". The show will allegedly focus on Kourtney Kardashian's children Mason, Penelope and Reign, Kim Kardashian's kids North and Saint, as well as Rob Kardashian's unborn baby.

According to Life & Style, Kris' concept for a next generation spin-off has ignited a "family war" as Kanye West has no plans on letting his two kids participate. "Kanye went ballistic when he heard the idea and went straight over to Kris' house to confront her," an insider shares, "He accused her of trying to exploit North and Saint."

While the Kardashian-Jenner momager is willing to wait until the kids are older to film the series, Kanye is completely against it. "He thinks North and Saint are too young. He's furious at the prospect," the insider says, adding that the "Famous" rapper "doesn't see this as an acceptable way to make a buck." Kris, however, "thinks she'll be able to change his mind," according to the insider.

While Kris hasn't commented on the report yet, another source tells Gossip Cop that the Life & Style story is "not true." According to the source, the momager has not proposed a reality series called "Keeping Up With The Kids" and the alleged feud between her and Kanye never actually happened.
