Caitlyn Jenner has been on cloud nine since coming out as transgender June 1 and she’s not letting anyone -- including haters like her former son-in-law Kris Humphries -- keep her down. In April 2015, Kim Kardashian's ex-husband, tweeted about how thankful he was to have escaped the Kardashian-Jenner family before Caitlyn, 65, then Bruce, came out. This prompted a slurry of hate as Caitlyn supporters demanded Humphries, 30, retract his comments. Although several months have passed, it seems Caitlyn hasn’t forgotten his hurtful words.

According to Us Weekly, the former Olympian will discuss the tweet at length with Kourtney Kardashian's now ex-boyfriend Scott Disick during episode 5 of his docuseries, “I Am Cait.” In the clip, Caitlyn and Scott, 32, are shown sitting down for a heartfelt chat about her transition at her Malibu mansion. During the conversation Caitlyn asks Scott how he thinks other men perceive her post-transition. The father of three hesitates, but eventually answers honestly, admitting that most men will probably not be “as comfortable” around Caitlyn as he is. This prompts Caitlyn to bring up Humphries’ tweet, which Scott was unaware of.

“Kris...idiot Humphries tweets, ‘Thank God I got out of that family in time.’ And just got absolutely ripped, just ripped. To the point that four hours later, he had to apologize,” Caitlyn explained.

The tweet in question was sent on April 25, the day after Caitlyn, who had not begun her physical transition yet, sat down with Diane Sawyer to reveal that she was indeed transgender. According to Us, Humphries tweeted that he was thankful that he “got out” when he did adding, “#Gottadoyou.” The tweet was met with much backlash from other users and, as Caitlyn said in the clip, he eventually clarified his comments. In a second tweet he explained that he always had and “always will” support his ex-father-in-law. Humphries went on to apologize for coming across “too vague,” ending his message with “#FullySupportBruce.”
