Scott Disick left his loved ones concerned for his welfare after he went "missing".
Scott Disick
The 'Keeping Up With The Kardashians' star was meant to be enjoying dinner with Kourtney Kardashian, his former partner and the mother of his three children - Mason, six, Penelope, three and 16-month-old Reign, but he didn't show.
In scenes aired on the most recent episode of the family's E! reality show, Kourtney said: "We were supposed to have a nice family dinner together with Scott but he's gone missing.
"There's definitely times when he'll take a few steps forward and then a few steps backwards. And it's just like this cycle that has been going on for years, and that's finally why I have to step out of it."
When Kris asked where Scott was, Kourtney added: "I called him when I was going to pick up Mason from school and he and Tyga have been hanging out at his house. All day and night."
Meanwhile, momager Kris went on to express her "disappointment" about Scott's recent behaviour but Kylie Jenner seemed less than impressed that her mother was criticising her boyfriend Tyga.
Kris said: "I thought Scott was finding his way and his balance - I'm really disappointed and worried about him. It breaks my heart ...
"I almost called T screaming at the absolute top of my lungs. You don't even know what would have gone down."
To which Kylie added: "I know Kourtney gets mad at Tyga sometimes and redirects her anger towards him since Tyga and Scott are together all the time so I'm kind of stuck between a rock and a hard place."
Kourtney, 37, then went on to insist Scott "just needs to grow up" for the sake of their three children.
She added: "He just needs to grow up. But I'm saying not for me but for my kids. Scott really needs to want to get his life in the right direction for himself but I just don't want Tyga to be a negative influence on Scott, so it just gives me a bad taste in my mouth.
"It just p****s me off that people like Tyga should know better. That are close to our family. That don't just find some other friends."
