'I was hysterically crying': Kim Kardashian recalls seeing for first time stepdad Bruce Jenner with women's clothes

Kim Kardashian recalls the time she caught stepdad Bruce Jenner wearing women's clothes.During an interview on The Alec Baldwin Show on Sunday the 30 Rock star recalled the time Bruce was the track coach at his daughter Ireland's school.

'When I knew him and he was married to Kris and would take the girls to school there was not a drop of Caitlyn in him,' Alec said referring to Bruce's new identity, Caitlyn Jenner.

When it happened I was "What?" not with any judgement I just did not see it coming.' the 60-year-old actor added.

Kim also revealed that she didn't know for a long time but accidentally walked in on Bruce dresses in women's clothes.

She told Alec, 'Nothing. I found out when I was maybe 25 and I walked in on Caitlyn, I mean it was Bruce but dressed up as a woman in the garage at my mom's house,'

'I ran in and packed a bag so fast, I was shaking and ran out and called Kourtney and said "I have to come spend the weekend with you" and was hysterically crying.

'She was like "What is it did you catch Bruce cheating?" and I was like "I wish. I don't know what I just saw."

Kim revealed that Bruce addressed the matter with her and swore her to secrecy until he was ready to be more open about it.

'It was Bruce then and he called me and said "One day I will sit down and explain all this to you but until then please do not tell a soul and do not tell your mother she will kill me."

Kim said that she did not want to break up her mother's marriage and leave her little sisters Kendall and Kylie without a father, so she kept quiet about it.

'I thought, "Okay, if I tell her I’m going to break up their marriage and my little sisters aren't going to have their dad around, so I better keep my mouth shut,' Kim said. 'I didn’t say a word.' 

Caitlyn unveiled her new identity to the world in July 2015 on the cover of Vanity Fair after months of speculation that the the former Olympic champion was transitioning to a woman.
