KUWTK fans will of course know that Caitlyn was previously married to Kardashian matriarch Kris Jenner from 1991 to 2015 – acting as stepdad to Khloe, her sisters Kim and Kourtney and brother Rob, as well as fathering two more children with Kris; daughters Kendall and Kylie.
Following Bruce and Kris’ split, the former Olympian transitioned and now goes by the name Caitlyn.
Despite the Kardashian clan initially supporting Caitlyn’s transition, things quickly turned nasty when the transgender star slammed Kris in her tell-all memoir The Secrets of my Life.
“It is so shady that Caitlyn came over and gave me the book and then on the phone she said, ‘Well, the final version has a few more things in it. But don’t worry, it’s nothing about you,’” Kim, now 39, told Kourtney, now 40, and Khloé on a September 2017 episode of Keeping Up With the Kardashians. “I have always had Caitlyn’s back. She is a liar. She is not a good person.”
However, it appears tensions may have simmered with one member of the family at least.
On Monday, Kim took to social media to share a sweet post marking Caitlyn’s birthday.
“Happy 70th birthday Caitlyn Jenner. I love you forever,” she captioned a throwback photo of the pair.
