The Poosh founder’s happily-ever-after with fiancé Travis Barker will be heavily featured, but her ex Scott’s role in the new show seems to be uncertain — although he has been seen in recent previews.

Nevertheless, sources revealed his relationship with the family has changed now that the Blink-182 rocker proposed to Kourtney.

While “the Kardashians adore Scott and tell him he’s part of the family no matter what,” the father-of-three — who shares Mason, 11, Penelope, 9, and Reign, 6 with the KUWTK alum — “feels very distant and feels like an outcast more than ever,” a source spilled.
