The 35-year-old posted a flashback pic on Instagram Friday, showing her and Disick and a bunch of friends including Girls Gone Wild creator Joe Francis. "The night I met @letthelordbewith you," she captioned the photo.
The pair met at Francis' house in Mexico in 2006, but Kardashian admitted on an episode of Kourtney & Khloé Take the Hamptons last year that it wasn't exactly love at first sight.
"I liked her," Disick remembered, "But she wanted nothing to do with me."
"I just thought he was so annoying," she explained. "He was four years younger, he lived in New York, he didn't have a job."
"Three kids later, still no job, still no idea where it's going," Disick said with a laugh.
Disick, who has battled alcohol problems in the past, checked into a Costa Rican rehab facility earlier this month.
"I think the thing that's most important to me is just his commitment to working on himself," Kardashian told PEOPLE. "If somebody doesn't want to make changes then that's really hard."
