Kendall Jenner, and Kylie Jenner being in attendance, Khloe confirmed her distaste for her former stepdad by being a no-show to the birthday soirée.

Since their show first aired in 2007, the Kardashian/Jenner family has been Caitlyn Jenner publicly came out as a trans woman in April 2015. Her new name, Caitlyn Jenner, was publicly announced in July of that year and by the following september, her name and gender were legally changed. While her children have been ive of her transition, it was Caitlyn's 2017 memoir "Secrets of My Life" that put her at odds with Khloé after Caitlyn bashed her ex-wife Kris Jenner in the book, Khloé's mother.

Now, two years later and Khloé made it pretty obvious that there is still tension between her and Caitlyn by skipping out on her 70th birthday party. Caitlyn celebrated her 70th birthday with her family on Tuesday, October 29. Kim Kardashian shared moments from the dinner on her Instagram Story. The Kourtney Kardashian sang "Happy Birthday" to Caitlyn. Kim went on to share a group photo from the birthday party that included her siblings and Caitlyn, but Khloé was noticeably absent. Prior to the birthday party, the Revenge Body host wrote on her own Instagram Story that she was busy “shooting a commercial all day.” But when considering her past issues with Caitlyn, her absence has left many speculating as to whyKhloé's absence from Caitlyn's party also comes one week after a source told Us Weekly that Caitlyn backed out of the Seminole Hard Rock Hotel & Casino opening in Hollywood because of a conflict with Khloé and Scott Disick

It was less than one year ago when Khloé tried convincing Kim to disinvite the former athlete from the family's annual Christmas Eve party in December 2018. At the time, Khloe asked her sister, "Who wants mom’s peace? ‘Cause that’s what matters. Do we care about Caitlyn’s peace when she’s never cared about ours?" While Kim itted to making “a big f–king mistake” by inviting Caitlyn, Kris said she was “fine”, while adding, "Just let it go. Vodka’s my friend." Back in May, Khloe shared her thoughts on Caitlyn's "really sweet" girlfriend, Sophia Hutchins, saying, “She’s younger, but like, she’s not bothering anyone." She revealed, "I think we’ve really come a long way. It was a struggle for all of us … not because she was transitioning. I think from just how it was all handled."

It remains to be seen if this birthday snub will affect their relationship or if it was genuinily just beacuase of conflicting scheduled. So, we'll see if the Keeping Up With the Kardashians camera will share if it was just a commercial that caused Khloé to miss Cailtyn's birthday party.
