Kardashian matriarch Kris is seen having an emotional chat with her daughter Kim Kardashian about former husband Bruce.
Kim tells her: "He has to deal with this for the rest of his entire life. Waking up and feeling like, 'Woah! This isn't my body. This doesn't feel comfortable.' That's the only way I can kind of imagine it. And you really have to let go."
But Kris, who divorced Bruce in 2014 after 22 years of marriage, finds it difficult to let go and soon breaks down in tears.
While sitting on the bed with Kim, 59-year-old Kris has tears streaming down her face as she tells Kim: "I have these memories of this life and I feel, sometimes, like it didn't exist."

The exclusive clip was aired on NBC's Today show as E! announced they would air a two-part special, Keeping up with the Kardashians: About Bruce.
Last month, former Olympian Bruce, 65, gave a two-hour interview with ABC where he confirmed ongoing rumours that he is transitioning into a woman.
He told Diane Sawyer, he said: "For all intents and purposes, I'm a woman. People look at me differently. They see you as this macho male, but my heart and my soul and everything that I do in life - it is part of me.
"That female side is part of me. That's who I am."
