family trip to Australia, confessing in a recent episode of The Kardashians that his decision to skip the vacation and remain home with his father had ‘made her really sad’.

Now, insiders are lifting the lid on 41-year-old Scott’s feelings about the apparent rift between Mason and Kourtney, 45, claiming that the reality star fears his ex is at risk of ‘creating a deeper divide’ with all of their shared children by cutting their dad out of their family trips with her new partner Travis, 48. Scott knows that Mason didn’t want to go on vacation with his mom because of Travis,’ a source told DailyMail.com.

‘Before Travis came along, Scott and Kourtney were vacationing together with the kids – not as a couple, but as friends who were both dedicated to their kids. 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.
