But it's "definitely not a relationship".

Kourtney Kardashian is back "casually dating" her first serious boyfriend since splitting from the father of her three children, Scott Disick - a source tells People. The pair were seen sharing a PDA moment in Los Angeles during the week, leading people to speculate they were seeing eachother again. Kourtney dated French model, Younes for two years before calling things off in August 2018. According to reports, Younes drove a wedge between Kourtney and the Kardashians as she "was always so private and closed off when it came to Younes, and that really distanced herself from her sisters.” Younes also apparently hated when Kourtney posted NSFW photos on her Instagram, leading them to have a great number of arguements towards the end of their relationship. But in the latest season of KUWTK, Khloe invited Younes to Kourtney's 40th birthday bash showing that the pair were in fact still in contact. And although Kourtney apparently only said hi to her former flame at the party, it looks like things have been on the up ever since then as they looked smitten together in Los Angeles this week. “You could call it casually dating. It’s definitely not a relationship. They have known each other for a long time and Kourtney has fun with him,” the source told People. And while things seem to be on the up for Kourtney and Younes again, things are as strong as ever for Scott Disick and girlfriend, Sofia Richie. Sofia was Scott's first serious girlfriend since splitting from Kourtney after nine years. The pair who've just celebrated Sofia's 21st birthday now live together in Los Angeles. And although it seemed to take the family a while to accept the relationship between Sofia and Scott, they are now happy for both of them with Sofia and Kylie Jenner once again, closer than ever.
