The drama is far from over between Kris and Caitlyn Jenner. Even after they have officially met and spoken about their issues, they continue to bicker and affect their kids. In this week’s episode of “Keeping Up With the Kardashians,” their conflict threatens to ruin Kylie Jenner’s 18th birthday celebration. [Warning: Spoiler Alert]

“Between you and Caitlyn, it’s just weird,” says Kylie, as she speaks to Kris about her birthday plans in a sneak peek shared by E! Online. She is planning her birthday dinner with her family, and Kylie is clearly unsure if it’s a good idea to have both her parents in attendance.

Her fears are validated when the daggers are immediately thrown between Caitlyn and Kris during dinner. Caitlyn arrives late and the Kardashian girls say that Bruce was never late. Kris comments that Caitlyn was probably delayed because she was still trying to get her look together. [scroll down for video]

“It’s a woman’s prerogative to be a little late,” says Caitlyn, who clearly isn’t pleased with Kris’ comment. “This is exactly what I wanted to avoid,” says Kylie. Earlier in the season, Kendall and Kylie also opened up about their issues, when they had to choose between their parents during Caitlyn’s appearance at the 2015 ESPY Awards.

In another sneak peek, Kylie also found herself in a tough spot, when Khloe and Kourtney confront her about her birthday party. Apart from the family dinner, the girls found out that Kylie is planning a big party. They wonder why they have not been invited and promptly call their sister asking for an explanation. Luckily, Kylie has an explanation. She says that she hasn’t figured out all the details yet and she hasn’t formally invited anyone. Kourtney and Khloe accept her explanation, but they still give her a hard time by saying that they might be busy on her birthday.
