Caitlyn Jenner was noticeably absent from Khloé Kardashian’s birthday bash in Hollywood on Monday, June 27, and sources tell Us Weekly that her no-show was telling.

“Caitlyn and Khloé aren’t currently speaking,” sources tell Us. “Because they aren’t as close, it wouldn’t make sense for Caitlyn to be t. That being said, if Caitlyn really wanted to come, Khloé would have allowed her because she wouldn’t have wanted to hurt Kendall and Kylie.”

The former Kocktails With Khloé host and Caitlyn, 66, famously butted heads after Khloé claimed during a January interview with SiriusXM’s Howard Stern that the I Am Cait star lied to the family about her transition.

“People would think that we were lying. But no, we believed him,” she explained of Caitlyn, adding that she and the rest of the family first found out about the former Olympian’s plans to transition during a business meeting.

Khloé also added that, at the time, Caitlyn’s decision to keep her big news from the family felt like a stab in the back.

In May, a scene on the season 12 premiere of Keeping Up With the Kardashians showed a stressed Kris Jenner on the phone with her ex, who was understandably furious over Khloé’s comments and had sent her stepdaughter some angry texts.

“Well, she’s out t talking s‑‑t about me,” Caitlyn said angrily over the phone.
