Scott Disick is never shy when it comes to speaking his mind (isn’t that why he was so often regarded as the *best* part of Keeping Up with the Kardashians?!) which is why we weren’t surprised to hear that he has already weighed in on 42-year-old ex-girlfriend Kourtney Kardashian’s very public desire to have a baby with her fiancé Travis Barker.

Akin to his reaction when he heard that the mother of his three children – Mason, 12, Penelope, 9, and Reign, 7 – was dating and then engaged to the 46-year-old Blink 182 drummer, the 38-year-old Flip It Like Disick star hasn’t held back, and is equally as (if not more!) vocal about his disapproval. An insider told Entertainment Tonight: “Kourtney and Travis want to have a child of their own together. It’s very important – and exciting – to them. Scott doesn’t like the idea of Kourtney and Travis growing their family, but the rest of the family is very supportive.”

The insider also confirmed that both Kourtney and Travis’ kids get along well, and they are reportedly excited about a new addition to the family. “Overall, the dynamic is supportive and healthy,” the source added, obviously not including Disick in the line-up as far as the “supportive and healthy” comment goes.

A separate source told US Weekly that Disick is also struggling to cope with the fact that Kourtney and Travis are getting married, as he reportedly always envisioned that if she ever did get married, it would be to him! “He feels like Kourtney was the one that got away and he still can’t wrap his head around the fact that they’re getting married soon,” the source said. “He feels like he’s not going to find someone like Kourtney. It’s going to take time for him to fully accept Travis is the one for her.”
