Fans Notice Khloé Kardashian Was the Only Sister Absent at Caitlyn Jenner's Birthday Party

This week, Caitlyn Jenner ushered in her 70th birthday with her daughters, her partner Sophia Hutchins, and even her step-daughters, Kim and Kourtney Kardashian. But Perez Hilton reports that fans were quick to notice that one Kardashian gal was not in attendance.

Khloé Kardashian was missing from the festivities, according to multiple Instagram posts and snaps. The 35-year-old Revenge Body host has had an estranged relationship with her former step-father since Caitlyn slammed Khloé’s mom, Kris Jenner, in her tell-all memoir The Secrets of My Life.

According to an older episode of Keeping Up With the Kardashians, Caitlyn showed Khloé a copy of the book, and then added the parts about Kris in before it went to publication. Khloé called the I Am Cait star out about the move, and said she was “a bad person.”

Though things seemed to calm down between the two reality stars, news broke this week that Caitlyn reportedly cancelled an appearance at the Hard Rock Café Hotel & Casino in Hollywood, Florida to avoid seeing her step-daughter, as well as her former son-in-law, Scott Disick, who also did not attend her birthday bash.

Sound like some classic Kardashian-Jenner family drama. Though things might still be rough between the two, we hope Caitlyn had a birthday fit for a gold medalist!
