Caitlyn Jenner thinks Ellen DeGeneres "alienated" her from the LGBTQ community.
The 67-year-old American television personality - who was formerly known as Bruce Jenner before she underwent a gender reassignment - admitted to the talk show host that she had been hesitant to accept gay marriage in the past during an appearance in 2015, prompting the blonde star to describe her guest's views as "confusing" in a later interview with radio presenter Howard Stern.
In her memoir, The Secrets of My Life, which has been obtained by Radar Online, Caitlyn says Ellen, 59, asked in a "friendly voice" to discuss her her views on marriage equality has "progressed over the years."
Caitlyn wrote: "I believed, as anyone would, that that was exactly what she wanted to talk about my progression in terms of changing attitude over the years."
"I am for it. I did not initially understand why marriage was so important, influenced not doubt by my own personal experience. Now I do, and it's a wonderful thing to see."
"This discussion further alienated me from members of the LGBTQ community. Ellen's appearance on 'The Howard Stern Show', where in my mind she even more emphatically took what I said out of context, made it go viral."
The I Am Cait star - who has six children and has been married three times in the past - had admitted during her interview with Ellen that she was a "traditionalist" who never used to approve of same-sex marriage, but her attitude had changed in recent years.
She said: "I have to admit that I remember 15 years ago, 20 years ago, whenever it was that the whole gay marriage issue came up, I was not for it."
"I am a traditionalist. I mean, I'm older than most people in the audience. I like tradition and it's always been between a man and a woman and I'm thinking I don't' quite get it.
"But as time goes on, like a lot of people on this issue I've really changed thinking here, to I don't ever want to stand in front of anybody's happiness. That's not my job. OK. If that word marriage is really, really that important to you I can go with it."
When Ellen then accused her of being "still a little not on board" with the idea, Caitlyn replied:
"No I'm on board. It's going to be pretty much the law of the land. So I still feel like yeah, I'm OK with it. I don't want to stand in front of somebody's happiness."
