Did Kourtney Kardashian throw shade at Scott Disick's new relationship?

She continued: "I have to handle it when he's out photographed with a different hooker every day". On Sunday, the two were aboard a private plane together when a pal snapped a photo of the couple holding hands and kissing, which Richie added to her Instagram stories. Despite criticism due to their age difference and the reality star's notorious behavior, the two have not been shy about flaunting their relationship.

"Scott isn't treating this as a long-term relationship whatsoever", a source told People. "I'm just giving you a heads up, should I not do that?' And I'm like, 'Next time I won't, ' and he's like, 'There's gonna be a next time?!'"

The insider went on to reveal that Richie is "much more invested in the relationship" than Disick is. She's young and can be quite naïve. And though Kourtney's trip was ladies-only except for the occasional appearance of Joe Francis (who owned the house they were staying in), it was clear that Scott was extremely jealous. The TMZ has reported that she couldn't care less.

That is the case for Kourtney's latest salvo against her former boyfriend, the Mirror noted. Kourtney just wants Scott to be his old self.

"I'm scared to death, are you kidding me?" he said when asked about the relationship.

Disick often uses a jet to go to parties and Sofia's father Lionel lets his girl use luxury jets quite often, so it could have been either one of their jets.

Lionel said: 'Have I been in shock?!

Whilst he added in a confessional: "The last thing I want to do is really hear exactly what Kourt's doing on this Mexican getaway".

Kourtney thinks this fling with Sofia is a little weird, but nothing shocks her anymore.

Kardashian's intentions were definitely good, but all they did was incite an epic, obscenity-filled freak out during a phone conversation with her ex as she worked out with younger sister Khloé. The reality star is pictured attending the Kith Sport fashion show on Sep.
