Kourtney Kardashian's ex Scott Disick reportedly 'refuses' to be in the same room as Blink-182 drummer Travis Barker.

The father of Kourtney's three children apparently feels "like an outcast" since the Poosh founder announced her engagement to Travis and will do anything to avoid seeing them together.

A source told Us Weekly : "He avoids family get-togethers that Travis is at, and he has refused to be in the same room with him at times."

The source added that the Kardashians still "adore" Scott, but he prefers to keep his distance since Kourtney's bombshell.

"The Kardashians adore Scott and tell him he's part of the family no matter what, but he feels very distant and feels like an outcast more than ever," they said.

Kourtney and Travis got engaged on Sunday

Scott and Kourtney share Mason, 11, Penelope, nine, and Reign, six, and apparently the self-named Lord isn't looking forward to the Christmas holidays.

"It's fair to say the holidays this year are going to be rough and will be a battle over the kids,'" the source revealed.

Kourtney, 42, and Travis, 45, have enjoyed a steamy relationship since becoming official in February and the tattooed musician popped the question on Sunday, much to Kourtney's delight.

The father of two got down on one knee on a picture-perfect beach which was filled with roses and giant candles.

Kourtney was bowled over by the "forever" proposal and now Travis' future mom-in-law Kris Jenner has given her seal of approval.

The 65 year old shared a selection of sweet snaps of the pair with the caption "Congratulations to the most beautiful, adorable, affectionate, fabulous, made for each other couple in the world! Love you guys!!!!!! @kourtneykardash @travisbarker."

However an unlikely source said to be concerned about their pair's engagement is former Eastenders actress Jac Jossa.

Scott and Kourtney never married but share three children

She took to Instagram saying: "Listen, I'm really, really happy for Kourtney Kardashian. She looks like she's the happiest she's been in a really long time.

"But listen, I just need to know that Scott's okay. The first thing I thought when I saw that picture [the engagement ring] was like 'oh my God, poor Scott,' which probably shouldn't be the reaction. Good for her for moving on."
