Though he may not be a fan of the reality stars, Brody did show a little love for half-sisters Kendall and Kylie Jenner, who he ran into at a McDonald's party.

"Brody stopped by to chat with Kendall and Kylie as well as Scott [Disick] but then headed up to a balcony table above their poolside one," an insider tells the Daily Mail. "He just seemed far more interested in being with his girlfriend [Kaitlynn Carter]."

Kylie did end up posting a video to Snapchat featuring her older bro, joking that he was stalking her.
