Personal Life

Thanks to her reality shows, audiences were privy to the ups and downs of Kourtney's relationship with her long-term boyfriend, Scott Disick. The couple started dating in 2006. During the filming of Kourtney and Khloé Take Miami, the couple split temporarily. Before the show aired, the couple reunited and Kourtney discovered she was pregnant.

Kourtney and Scott's first child, a son named Mason Disick, was born on December 14, 2009. Kourtney gave birth to a girl named Penelope Scotland Disick on July 8, 2011. In June 2014, she revealed that she and Scott were expecting their third child. The couple welcomed a son, Reign Aston, on December 14, 2014 — the same day their son Mason celebrated his fifth birthday.

In 2015, the on-again, off-again couple reportedly split up over the Fourth of July weekend, according to E! News. The breakup came after tabloids reported that Disick, who was in and out of rehab facilities, was partying in Monte Carlo with other women, including his ex-girlfriend.

Kourtney later became involved with French model Younes Bendjima, who reportedly disapproved of her revealing social media photos. The pair split in August 2018, though they rekindled their romance the following year. 

Kardashian confirmed her relationship with Blink-182 drummer Travis Barker in early 2021.

Business Ventures

In addition to being a mother and reality show personality, Kourtney is a successful entrepreneur. She and her sisters ran a chain of clothing stores called DASH, before their April 2018 announcement that the stores would close. She also co-owned a children's boutique, Smooch, with her mother and collaborated with Kylie for new products through her younger sibling's cosmetics line.

Kourtney has also positioned herself as the most environmentally conscious member of the family. In April 2018, after accepting an invitation from the nonprofit Environmental Working Group, she participated in a congressional briefing on regulatory reform of the cosmetics industry, earning approval for using her "star power" to draw attention to the issue.

In April 2019, Kourtney launched a new lifestyle and wellness site, Poosh, with a stated mission to "educate, motivate, create, and curate a modern lifestyle, achievable by all."
