The first episode of Caitlyn Jenner's new reality show, I Am Cait, shows the Kardashian-Jenner clan rallying around her.
The show documents her life after her recent transition to living as a woman.
In the first episode, the 65-year-old admits: "Having that opportunity to just be honest with my family is like having a thousand pounds taken off my shoulders."
Jenner's famous stepdaughter Kim Kardashian also features on the show.
In one scene Kardashian phones to break the news of Jenner's record-breaking debut on Twitter, and says: "Just wanted you to know, I'm on the bandwagon."
Later, Jenner shows her around her walk-in wardrobe, saying: "I love this Tom Ford dress."
Kardashian laughs, commenting "Mom has that", while Jenner jokes: "I'd better wear it before she does".
Kylie Jenner also meets Caitlyn for the first time via video-chat, reassuring her: "You look pretty!"
The 17-year-old model later comes round to the house to meet Caitlyn in person for the first time, and sorts her out with green-dipped hair extensions.
The former athlete, known previously as Bruce Jenner, is most nervous about meeting her mother Esther for the first time post-transition.
Jenner's mother finds the transition difficult to accept, commenting: "I think he's a very good looking woman. He's still Bruce."
Jenner, who starred on the cover of Vanity Fair in June with the strapline Call Me Caitlyn, says: "It's great to be able to base a relationship with your family on honesty."
However, she explains that she felt lucky because "it's not been this way for everybody", and that she has a "tremendous responsibility" to speak about transgender issues because she has a public voice.
After talking to the mother of Kyler, a transgender 14-year-old who had recently killed himself, an emotional Jenner says: "Suicide is a permanent solution for a very temporary problem. I know how these kids can feel.
"I've had some very dark moments in my life and said: 'let's just end it right here'. No more pain, no more suffering. That struggle, it's real and I've been there."
But she adds: "I don't think I have ever been more excited about life than I am now, living my true identity."
I Am Cait airs on Sunday August 2 at 9pm on E!
