The transgender reality star participated in an in-depth interview with the television host, and explosively claims she once crossed dressed with ex-wife Kris Jenner.
The 68-year-old star. who was previously married to the Keeping Up with the Kardashians star for over 20 years, has admitted prior to marrying and undergoing gender reassignment surgery, the two 'dressed up' - but only on 'one occasion.'
The 62-year-old 'momager' has repeatedly denied knowing about the former Olympian's desire to live as a woman.
'I definitely told her, I even dressed up with her before we got married, only on one occasion,' Caitlyn asserted to Morgan. 'I had been on hormones for four and a half years...these are changes when you are on hormones which are tough to hide.'
Although Kris has claimed she was left in the dark about Caitlyn's desire to transition into a woman, Caitlyn has insisted she was always 'honest' with her former partner, even before the pair got intimate. Although Caitlyn claims she did 'downplay' her feelings.
Caitlyn, who has Kylie, 20, and Kendall, 21, with Kris and Brody, 34, and Brandon, 36, with previous partner Linda Thompson as well as Burt, 39 and Cassandra, 37, with Chrystie Jenner, said: 'I was honest to that point, I'm sure I downplayed it quite a bit but I was honest with her. I told her before I ever slept with her, she knew.'
Although Kris knew about Caitlyn's gender identity issues, The Secrets of My Life author has revealed that neither of them every thought she would actually go through with the full transition.'
The new claims come just days after Caitlyn revealed it had been a year since she had spoken to Kim Kardashian.
