Kim Kardashian: I know Bruce Jenner's female name, have seen him dressed as a woman

Now that Bruce Jenner has revealed he is transitioning into a woman, the Kardashian family is done keeping quiet about the Olympic athlete’s life changes.

Kim Kardashian spoke to the “Today” show right after Jenner’s sit-down with Diane Sawyer, and most-recently she sat down with “Access Hollywood” to speak more about the 65-year-old’s transition.

She said she recently met the person Jenner refers to as “Her.”

The reality star has yet to reveal his female name to the media, but Kardashian said she knows it.

“I do,” she said of his name. “I can’t tell you though.”

She shared her reaction to seeing Jenner dressed as “Her.”

“It was amazing and she looked beautiful, really beautiful,” she said. “She was dressed up, beautiful make-up, beautiful hair, very, very beautiful and very comfortable.”

Meanwhile, the rest of the Kardashian family shared their feelings about Jenner’s transition on the E! Special, “About Bruce,” which aired Sunday night.

"I just remember being little and not really knowing what was going on," 19-year-old Kendall Jenner told the cameras. "We would find things like makeup or lipstick, and we thought he was having an affair at one point, and we didn't know what to do. We didn't want our family to be broken up, so we wouldn’t tell anybody.”

Kendall Jenner and step-sister Khloe Kardashian are shown in tears at one point during the special, but Khloe Kardashian is also shown cheerfully bringing gifts to an emotional Bruce Jenner.

Meanwhile, ex-wife Kris Jenner revealed to the cameras she is having a hard time.

“I’m not OK. I don’t know how to handle this,” she tells Kim Kardashian through tears. “This is my life. I committed to this life, and I think that he just checked out.”

Kim Kardashian revealed to E! she knew something was going on with her step-father but kept it a secret for more than a decade.

“I just came home, and I walked in the garage to go to my bedroom and Bruce was dressed up like a woman,” she recalled. “I ran to Kourtney’s, and I was hysterical, crying. We had no idea what this is, or what this means. So I kept this secret, for maybe, you know, 12 years.”

GLAAD praised the E! special for giving viewers an inside look at what life is like for the family members of someone who is transgender.

"When a person transitions, their family and loved ones go through their own journey to acceptance," said GLAAD's Nick Adams. "In these specials, Jenner's family allowed viewers a glimpse of what that process sometimes looks like. As more families learn about what it means to be transgender, hopefully more trans people will find love and acceptance from those closest to them."

Part 2 of the E!’s “About Bruce” special will air Monday night.
