After Scott Disick spent his time in Cannes with a series of PDA sessions with a string of women, he has not seen their three children

Kourtney Kardashian needs Scott Disick to make a major change — or his relationship with his kids may suffer.

After Disick spent his time in Cannes with a series of P.D.A. sessions with a string of women, a source tells PEOPLE that Disick has not seen their his children — Mason, 7, Penelope, 4, and Reign, 2 — in weeks, and Kardashian has no intention of allowing a visit until he changes his act.

“Scott hasn’t seen the kids for weeks. Up until recently, it was his own choice. But now, even if he wanted to, Kourtney won’t let him see the kids unless he shapes up,” the insider says.

The source adds that the 38-year-old reality star is tired of going through the same cycle with her on-again, off-again boyfriend.

“She just can’t believe they are going down the same road again. It feels old to her,” the source says. “She used to worry about Scott, but not anymore. She just finds him absolutely pathetic. It’s obvious to everyone that he is a mess. She is wondering how long it will take this time before he comes crying and asks for forgiveness. She plans on being firm. Get help, or he won’t come near the kids.”

While Kardashian — who split with Disick in 2015 — was also out and about in the French Riviera spending time with model Younes Bendjima, Disick was spotted cuddling with 19-year-old actress Bella Thorne.

“Kourtney thinks that the idea of Scott and Bella dating is embarrassing, particularly because she’s so young,” a source previously told PEOPLE. “She also thinks Bella is a little trashy so the idea of the two of them dating definitely bothers her a bit.”

Disick was also spotted with two other young women over the next two days – stylist Chloe Bartoli and blogger Maggie Petrova. He also kissed a mystery brunette a few days later and was seen romping around with 18-year-old model Sofia Richie over the weekend.


On Sunday, the 34-year-old enjoyed the company of another woman in Monaco. Disick and the mysterious blonde beauty got close on the deck of a yacht.
