Former nanny Pam Behan revealed it "was not easy to work" with Kris Jenner as well as other "never-before-heard details" in the Kim Kardashian West-themed episode of Scandal Made Me Famous, which airs July 21 on the Reelz Channel.
According to the Daily Mail, the Pepperdine grad served as the 62-year-old momager's personal assistant as well as cooking and caring for her children - Kourtney, Kim, Khloé, and Robert - following Kris' 1991 wedding to second husband, Caitlyn (then Bruce).

"I liked Kris and I respected her for many reasons. She was not easy to work for because she was a perfectionist and she expected perfection," Pam explained in a sneak peek obtained by People.
"On a daily basis, when she has a very long list and you're fighting LA traffic and taking kids to their events, and maybe possibly not everything on the list gets done, there were a few moments where I got an earful.
"At first, I used to be just crushed when she would speak to me like that. But she vents, she speaks what's on her mind. She wasn't easy to work for, but I did enjoy my job."
In 2013, Behan - who also nannied Bruce & second wife Linda's sons Brandon and Brody - previously detailed her five-year employment in the 236-page tell-all, Malibu Nanny: Adventures Of The Former Kardashian Nanny.
37-year-old Kim was only 10 when Pam started the demanding job and the upcoming episode also covers Kardashian's first date, Vivid sex tape, and the murder charges surrounding her "Uncle O.J." Simpson.
On Saturday morning, the Ocean's 8 actress shared several Insta-stories of her five-month-old daughter Chicago and her five-year-old daughter North.
The Assembly Bill 2550 activist certainly had fun with various filters as she cuddled her privileged princesses.
In fact, it's rare for Kardashian to share images of her three children without the cartoon-ish filters.
You guys are so cute!' Kim - who boasts 201.6M social media followers - gushed.
"Ooh this one is really pretty. You both have little flower ears and little freckles. Say good morning! Love you girls!"
Noticeably absent from the selfie session was the half-Armenian beauty's two-year-old son Saint with her third husband, rapper-designer Kanye West.
But it wasn't long before the Calabasas socialite had to retire to her second home or rather her "office for the day" - the gym with fitness trainer Melissa Alcantara.
Kim will next release three new fragrances (smelling of cherry, watermelon, and peach) next Tuesday through her KKW Beauty brand.
The 15th season of Keeping Up with the Kardashians premieres August 5 as part of her family's massive $100M deal with the E! Network through 2020 - according to Variety.
