Los Angeles - Caitlyn Jenner "could never go back" to being Bruce.
The 65-year-old star - who underwent a gender transition earlier this year - has revealed a recent trip with three other transgender women was a "truly liberating experience" and made her realise she had made the right decision by becoming Caitlyn.
Asked about her favourite part of becoming a woman, she said: "Just being able to be myself. Recently I went on a trip with some of my new friends and I had such a wonderful time. I packed for the first time - as just Caitlyn, nobody else - which is the first time I've ever done that. I was gone for five days and had such a fantastic experience with all of these girls who have all been through the same thing.
"We had so many stories to tell. We had so many things that we were all dealing with. It was just truly a liberating experience. I knew then that I could never go back."
The former Olympic athlete made the comments in a new blog post on her website titled "The Future Looks Bright" in which she also said she felt "very uncomfortable" when she was Bruce and praised her fans for their "incredibly positive" reaction to her.
She added: "I knew that my transition would get some response, but I certainly never expected all of this. It's honestly been incredibly positive."
