Perhaps they assumed she wasn’t on the guest list?

Kylie Jenner recently revealed that her rowdy pooch posse ate Kendall Jenner‘s derrière.

“I have seven dogs, and they’re wild,” the makeup mogul told Hailey Bieber on her Halloween episode of “Who’s in my bathroom?”

“They just bit Kendall on the ass,” Kylie explained, much to Kendall’s surprise.

“They bit her on the ass?” exclaimed a wide-eyed Bieber.

The subject arose while Kylie, 25, was lovingly nuzzling Oscar, the adorable “Morkie” (Maltese-Yorkie) Hailey, 25, shares with husband Justin Bieber.

Earlier in the episode, Hailey and Kylie, who were dressed in matching witch costumes, discussed how the spooky holiday has changed for the “Kardashian” star since becoming a mother.

“All I want to do is go trick-or-treating with my kids,” she said. “It’s all about them now, whereas it was all about me before.” The subject arose while Kylie, 25, was lovingly nuzzling Oscar, the adorable “Morkie” (Maltese-Yorkie) Hailey, 25, shares with husband Justin Bieber.

The mother of two, who has a 4-year-old daughter, Stormi, and a nearly 9-month-old son with Travis Scott, told the Rhode skincare founder that celebrating Halloween is “more fun now” because she “get[s] to live through them.”

Scott, on the other hand, may have a different opinion.

Scott and Kylie’s relationship has appeared strained since Instagram model Rojean Kar claimed earlier this month that he had been unfaithful to his girlfriend.

The rapper categorically denied the accusation, while the businesswoman has yet to respond.
