Kourtney Kardashian's long-term partner, Scott Disick, was with her for nearly a decade, starting in 2006. During their relationship, they had three children: Mason, Penelope, and Reign. Despite their ups and downs, including a breakup in 2015, they maintained a co-parenting relationship and remained significant figures in each other's lives. Scott's involvement in Kourtney's life and their family dynamics made him a prominent partner in her story, distinguishing him from her later relationships with Kanye West and Travis Barker.
