Scott Disick attended a pre-birthday bash for Brody Jenner on Wednesday, even though he is presently estranged from much of the Keeping Up With the Kardashians family. The avid partier only drank beer at the event, which is way out of character for Scott Disick.

Sources at the party say Lord Disick was in a somber mood at Warwick in Hollywood–and he didn’t stay to celebrate very long.

“He was in a very somber state, dark energy,” one source says. “There were girls throwing themselves his way, and he wasn’t having it at all.”

“He huddled himself in the corner with his bodyguard,” the source adds. “He definitely wasn’t trying to draw any attention to himself. He didn’t really seem like he wanted to be there.”

Brody Jenner was DJ-ing his own birthday bash, and Scott Disick offered him a birthday hug when he arrived at the event.

Jenner is the half-brother of Kylie and Kendall Jenner–daughters of Caitlyn and Kris Jenner.

It seems Scott Disick isn’t the only one estranged from Kris Jenner’s side of the family.

“I don’t see them very often,” Brody he said during an interview last month. “I live out in Malibu, they live in Calabasas. That’s the one thing that people don’t really understand is that we live two completely separate lives. And everybody ties us in together as the Kardashians and the Jenners. I mean, [Kris and Caitlyn] got a divorce, so they’re not even technically my family anymore.”

As for Kourtney Kardashian taking Scott Disick back, that doesn’t seem too likely. A rather cryptic Tweet lends itself to a sense of satisfaction with her decision to break things off with the father of her three children–Reign, Penelope, and Mason Disick.

It looks like Scott Disick better get used to being miserable–or do something constructive with his life. Even though Kourtney Kardashian is encouraging him to have a relationship with his kids, it doesn’t look like she plans to resume the one they shared.
