Scott Disick chose to party in Vegas instead of gather with members of the Keeping Up With the Kardashians family in support of Bruce Jenner, when his interview with Diane Sawyer aired on Friday night.

Hollywood Life reports that Disick ‘ditched’ the gang and headed to Las Vegas instead. And while that’s not a big surprise–Scott Disick heading to Vegas–the reason he didn’t watch the interview with the family is surprising, in a very troubling way.

“Scott thinks the whole situation is weird and was talking to friends and cracking jokes about Bruce’s special throughout the night. He had no intention to watch the show with Bruce and the rest of the family and he doesn’t even want to watch the show now,” a source tells Hollywood Life.

Scott Disick and Kourtney Kardashian have been a couple for nine years and they have three children together. Scott has long been a member of the Jenner-Kardashian family, so it’s really rather shocking that he would refuse to support Bruce Jenner when he needed it the most.

Ugh. Scott Disick totally ditched Bruce Jenner's big family viewing and decided to go party instead. http://t.co/2AfL4izeuq

Some wonder now if Scott Disick ditching Bruce Jenner’s interview–and the family members who watched it together–will cause problems between him and Khloe and Kim Kardashian. They were both disgusted when Kim’s ex-husband Kris Humphries made a very unkind remark about Bruce.

Man, I'm glad I got out when I did. #Gottadoyou

Kris Humphries later apologized, but remains on Kim and Khloe Kardashian’s sh*t list for the insensitive comment.

Is Scott Disick the new leader on that list? How do you suppose Bruce Jenner feels about him not showing up to lend his support? Kourtney Kardashian can’t be too pleased either.
