She can cry if she wants to! In a preview for an upcoming episode of Keeping Up With the Kardashians, Kylie Jenner expressed her concern about having both her mom, Kris Jenner, and dad, Caitlyn Jenner, attend her upcoming 18th birthday celebrations.

In the clip, Kylie discusses her birthday plans with her mom. "We can do a family dinner for your birthday," Kris suggests.

"But between you and Caitlyn, it's just weird," Kylie replies.

The camera then cuts to Caitlyn arriving fashionably late to the family gathering. "Bruce was never late," Khloe Kardashian remarks.

"She was probably working on her look," Kris snipes.

Caitlyn, raising her eyebrows, replies: "It's a woman's prerogative to be a little late."

Watch the rest of the family react awkwardly in the video above, and tune in to Keeping Up With the Kardashians on E! this Sunday, Dec. 6, at 9 p.m. ET.
