Transcript for Meet Caitlyn Jenner
Today the world got its first look at Caitlyn Jenner, formerly known as Bruce Jenner, the olympic hero turned reality star who's now the most public face of the transgender community. Tonight the picture on the cover of "Vanity fair," the behind the scenes video of the photo shoot and the instant global reaction. As soon as the "Vanity fair" cover comes out, I'm free. Reporter: For years, 65-year-old Bruce Jenner referred to his real self simply as "Her" but today, finally, her has a name. This is Caitlyn. This is about your life. Bruce always had to tell a lie. He was always living that lie. Every day he always had a secret from morning until night. Caitlyn doesn't have any secrets. Reporter: She came out in classic Jenner style in as public a forum as a you can imagine. The first pictures on the cover of "Vanity fair" taken by the famed photographer Annie Leibowitz in Jenner's Holm home in malibu. The way she looks now, an extraordinary contrast though the one-time olympic champ. I was probably at the games because I was running from things. Reporter: This is a behind the scenes look at Caitlyn's "Vanity fair" shoot, Jenner in full makeup, designer gowns, bearing her shoulders and chest and showing leg as well. Today her inaugural tweet "I'm so happy after such a long struggle to be living my true self. Welcome to the world Caitlyn. I can't wait for you to get to know her/me." Jenner spoke about her transition in this emotional interview. It will be an emotional roller coast ier but somehow I will get through it. Reporter: With Diane sawyer this past spring watched by 20 million people. Are you a woman? Yes, for all intents and purposes, I'm a woman. Reporter: On the show "Keeping up with the kardashians" she discussed with family members how her looks would soon begin to change. It's a lot of work. Okay. You do it in stages. You probably didn't even notice. You got a nose job. I noticed. I noticed. Reporter: According to "Vanity fair" Jenner went under the knife for what is known as facial femininization surgery saying she had a panic attack recovering at home. She thought what did I do to myself. With all said, there was one topic Jenner told Diane sawyer she would never talk about publicly, the sexual reassignment surgery. I would do it so quietly, nobody in the world would ever know. I'm not shooting this or filming anything. To me it is degrading. At this point, as far as the term srs, sexual reassignment surgery, would be down the line, you know, down the line. Reporter: Jenner told the writer from "Vanity fair" she has not yet undergone that surgery, but for Caitlyn and others in the transgender community it is more than just surgery. We should not be defined by an operation. We should be defined by our humanity and dignity and that's what is changing. Reporter: This week on "Keeping up with the kardashians" the last images of Jenner as Bruce. I want to say hi to Bruce and get my last visual of him that I want without some major physical changes. Give me a hug. Love you guys. Reporter: Today for children all showing their love and support on social media. Kendall Jenner the 19-year-old supermodel tweeting be free now pretty bird. The rest of the Kardashian clan -- Khloe tweeting, we were given this life because you were strong enough to live it. Support from Caitlyn pouring in from social media. Her Twitter account reached 4 million in four hours, faster than president Obama, Justin Bieber or Taylor swift hit that milestone. Caitlyn Jenner became the number one trending topic in America than world. Today was a milestone moment in what has been a series of milestone moments for the transgender community. We are seeing somebody transition who almost every household knows, and the most important thing, I think, is that we can get to know somebody who's transgender and let it not be as big of a deal. Reporter: Film maker Kimberly Reid grew up as a boy named Paul and a starting quarterback on her high school football team. Part of me presenting a masculine or athletic character to the world, part of that was me trying to prove to myself and everybody else around me that I wasn't transgender. Reporter: Caitlyn's transition is perhaps the most public in the history of the transgender community. Do you feel a little bit as if you are saying good-bye to something? Am I saying good-bye to something? I'm saying good-bye to people's perception of me and who I am. I'm not saying good-bye to me because this has always been me. Reporter: For Kris, Jenner's wife of almost 25 years, this appears to have been a rocky time. I'm trying so hard to just process my pain and get through my days. It's a struggle. All I have really is my memories. I look at pictures of you and the kids and I get really sad because I feel like you died. Bruce died. Honestly, I'm not going anywhere. Things may change but I still want to be a part of your life. Reporter: Caitlyn said she told Kris her situation before they got married. I had been on hormones for five years and it was a good solid 36-b, something. So you can't really, you know -- you can't hide those things. And she goes, well, you know, okay. You know, you like to wear women's clothes and I'm going -- I kind of down played it some. Reporter: According to "Vanity fair," Kris said it was comparable to a little man boob situation but no B cup going on. Caitlyn said she has apologized for all she did not say but even now her biggest worry, she says is for her children. This season on a special episode of "Keeping up with the kargs" the girls share their ongoing frustrations with their father. Were you planning on not being Bruce anytime soon? That's quite possible, yeah. That's something we all need to know. I don't think you can say -- like you have children. You don't need permission but you need to tell us. I talked to my kids and told you what I was going through. I thought it was understood. Reporter: His biological children grappling with something so new. I held his hand and cried with him and told him how proud of him I was and how inspired I was. First thing I thought is oh, it finally makes skens sense. I asked him what do you want us to call you and he interrupted me and said, I'm dad. I will always be your dad. And that was a huge relief. Reporter: They along with the other kids will join Caitlyn for her first public appearance at the ESPN espys on July 15th. She will accept the Arthur ashe courage award. Even as much as they support her, the older Jenner kids won't be appearing in Caitlyn's upcoming docu-series on E! My whole life has prepared me for this moment. I want to take advantage of it. I want to do the right thing. And be true to myself. What I'm doing is going to do some good and we're going to change the world. I really firmly believe that. Reporter: With this step, perhaps she already has.
