Scott Disick feels ex-Kourtney Kardashian’s unwillingness to continue vacationing together is causing a ‘deeper rift’ with their shared children, notably their eldest son Mason, according to insiders close to the reality star family.

Kourtney was distraught when her 14-year-old son Mason declined to accompany her and her husband Travis Barker on a family trip to Australia, saying on a recent episode of The Kardashians that his decision to stay at home with his father had’made her incredibly unhappy’.

Scott Disick feels that his ex Kourtney Kardashian’s unwillingness to continue vacationing together is producing a ‘deeper rift’ with their children, notably their eldest son Mason, insiders say.

Insiders are now spilling the beans on 41-year-old Scott’s feelings about Mason and Kourtney’s apparent schism, claiming that the reality star is concerned that his ex is risking ‘creating a deeper divide’ with all of their shared children by excluding him from their family trips with her new partner Travis.

‘Scott knows Mason didn’t want to go on vacation with his mom because of Travis,’ a source said.

‘Before Travis came around, Scott and Kourtney were traveling with the kids – not as a relationship, but as friends who were both committed to their children.

Days after it was revealed that Mason, 14, had refused to join Kourtney and new husband Travis Barker on vacation, Scott shared an image of himself with the teen, calling him his ‘best friend’

Their father-son getaway came just one week after Kourtney, 45, admitted that Mason ‘refused’ to go on vacation to Australia with her, Travis, 48, and his other siblings

‘This is obviously not going to happen again and Scott thinks that Travis should not have a problem with family vacations if he was comfortable in his marriage. Heck, he could even come if he wanted to.’

‘Instead of doing co-parenting the way that they used to, Scott believes that she is creating a deeper divide between herself and her kids with Scott,’ the source revealed.

‘Mason is a classic example of this. He lives with his dad and Scott would gladly let any of his children live with him. It is a much more stable environment.’

DailyMail.com has contacted spokespersons for Scott, Kourtney, and Travis for comment.

Scott made clear his incredibly close bond with Mason earlier this week when he shared an image of the two of them traveling home from vacation together on a private jet, referring to the teen as his ‘best friend [for] life’.

The photo was all the more significant given that it was shared just days after Kourtney was seen voicing her heartache over Mason’s refusal to join her and Travis in Australia, where the traveled with her and Scott’s children Penelope, 12, and Reign, nine, as well as their newborn Rocky.

Then, on the most recent episode of The Kardashians, which aired on Thursday, Mason and Kourtney were seen having an awkward exchange, during which the teen appeared to avoid hugging his mom.

Kourtney looked delighted to see him. As she approached him for a hug, she belted out, ‘My son.’

As she wrapper her arms around Mason to give him a squeeze, the teen kept his hands in his pockets and did not hug her back.

Scott and Kourtney (with Mason, Penelope, 12, and and Reign, nine) used to vacation together with their three kids often following their split in 2015 and were very amicable co-parents

‘When Travis got together with Kourtney on the heels of her and Scott’s long romance, he felt threatened by Scott,’ the source said.

‘Travis made it awkward for Scott to be around the family when he was there. His constant kissing and groping of Kourtney was his weapon and he knew that it would keep Scott out of the picture – and it did at the time.

‘Travis needed Scott to know that Kourtney was his now and, as a result, it caused Scott to distance himself from the Kardashians.’

Kourtney started dating Scott in 2006 and their tumultuous relationship was chronicled on the former E! reality show, Keeping up with the Kardashians, with the couple facing cheating allegations and his rehab stints as well as breaking up multiple times before they finally called it quits in 2015.

Scott continued to feature on the show as they navigated co-parenting, and the father-of-three – known affectionately as ‘Lord Disick’ – remained close to Kourtney’s family.

But when the show rebranded to The Kardashians and jumped ship to Hulu in 2022, Kourtney’s relationship with Travis was in full force and Scott revealed he was no longer as close to his ex, admitting it had been ‘a huge adjustment losing her as a best friend.’

Kourtney expressed her sadness over Mason’s refusal to join them in Australia during a recent episode of The Kardashians (Kourtney, Penelope and Reign seen in Australia without Mason)

Kourtney said during the recent season five episode (pictured here) that Mason was ‘home with his dad, which makes me really sad, but I’m making the most of every second.’

Kourtney and Travis (seen in 2022) started dating in 2021. She and Scott separated in 2015, and a source told DailyMail.com that their PDA’made it unpleasant’ for Scott.

‘He understands that the Kardashians’ devotion is with Scott. Kourtney and Scott’s children are likewise extremely devoted to their father and will always support Scott when it comes to Travis’ problems with his father.
