Bruce Jenner Sex Change: More revelations on About Bruce special as fans show support for reality TV's first family

Bruce Jenner was trending on Twitter again as the Keeping Up With the Kardashians special About Bruce was aired on British and US TV.

The emotional programme saw the former Olympic athlete open up to his family for the first-time about his plans to undergo gender reassignment.

The candid episode of the popular reality show, which was filmed in January, revealed the reactions of his family and their concerns as they laughed and cried toegther.

"My biggest fear about meeting her for the first time is just I think my reaction. I'm very facially expressive," Khloé Kardashian, 30, said. "I don't want to do anything offensive that would hurt her feelings."

Recognising their concerns and expressing his own fears for his children, Jenner commented: "They're all kind of nervous to meet her. She's always more fun, more at ease and feeling good about herself. It's all part of me. It's like having Bruce with a little icing on the cake. It only gets better."

Since the programme was recorded, Kim Kardashian West, who has been described as the most supportive following Bruce's revelations, recently revealed that she has seen her step-father as a woman. In an interview the 33-year-old said: "She is beautiful."

There were also several startling revelations as the family opened up to one another about their suspicions .

In the first part of the special, Kendall Jenner, 19, recalled how she and her younger sister Kylie Jenner, 17, found their father's makeup around their home and mistakenly believed he was having an affair.

"We didn't want our family to be broken up, so we didn't tell anybody," Kendall said.

In another bombshell, the 65-year-old revealed that he was almost outed three decades ago when a reporter apparently caught him dressed in women's clothes. Bruce "begged" the journalist not to publish the story, and he agreed.

Kourtney Kardashian revealed that her children and Kim and Kanye's daughter North, have not been told of the changes their grandfather is undergoing as he transitions into a woman, since they are too young to understand.

North West turns 2 next month, while Kourtney's children with Scott Disick, are 2½-year-old Penelope and 5-month-old Reign Disick. She revealed however, that Mason, 5, is more aware of the situation than his parents realize.

"I think we are waiting to see what Bruce does before we tell Mason," the 36-year-old said in part 2 of About Bruce.

She explained that she and partner Disick intend to explain the meaning of "transgender" to their son and believe Bruce's example will teach him an important lesson about never judging people. They believe he should hear about Bruce's transition from them and not from children at school.

Scott, who has been praised for his maturity in supporting Bruce said: "It's only a positive thing for my son and my daughter to know all these different things that go on in the world.You only really get one chance at this life, so whatever you gotta do to be happy, [you do]."

Wearing his long hair tied back in a pony tail, Bruce also revealed that he always hated having to cut his hair short and plans to fully transition this spring, but isn't quite ready for sex reassignment surgery.

Commenting on his relationship with his ex-wife Kris Jenner, who he was married to for 22 years he said simply: "I will always love her."

Viewers and fans watching the emotional episode showed their support for the family on social media.

"I'm watching #AboutBruce and I'm holding back so many tears, Bruce Jenner is such a courageous, inspirational and wonderful human being," said one viewer.

" #KUWTK #AboutBruce I've always loved Bruce and I'm so happy seeing him becoming herself &the acceptance from all the family is inspiring," wrote another.

"I've just finished watching part two of #AboutBruce and I'm honestly so moved and grateful to have someone that inspiring in this world," said a fan.

Meanwhile, describing how it feels to finally live as he always felt he was meant to be, Bruce said: "There's nothing like freeing your soul and surrounding yourself with people that make you feel good about yourself. It's pretty wild that you're gonna live two lives in one lifetime. I can't die and not experience her. Today my family loves, supports and accepts me as I am and I am so grateful."
