Kris Jenner sends her family a Bible verse every morning.
Kim Kardashian West
The 62-year-old matriarch has a text group with her children - which includes daughters Kim Kardashian West, Khloe and Kourtney Kardashian, and Kylie and Kendall Jenner, and son Rob Kardashian - and the whole clan are "really religious" and dedicated to their Christian faith.
Kim said: "We don't share it much, but we're really religious. We start our day with a group chat with a Bible verse from my mom, and everyone chimes in on the meaning of it.
"We are very Christian - and our work ethic and our discipline comes from so many years at Catholic school."
And Kim - who has children North, four, Saint, two, and four-month-old Chicago with husband Kanye West - credits her education at the all-girls Marymount High School in Los Angeles for instilling many of the values she lives by as an adult.
She told Vogue.com: "I had an amazing Catholic school experience. It's very strict, very punctual, and I like that--it's how I've lived my life."
The 'Keeping Up With the Kardashians' star had a "typical preppy" look when she was at school, and though she followed the rules, she couldn't resist making her uniform shorter, much to the annoyance of her teachers.
She admitted: "I stuck to the rules, except for my really short skirt--I was always getting into trouble for that. I was, like, full-on 'Clueless'."
Last month, Kim was excited to attend a high school reunion in honour of the 20 years since her senior year.
She said in a clip posted on her Instagram Story: "So my friends are worried that we're gonna run into people that they were mean to and I feel so good about my conscience that I was so nice to everyone."
At the reunion, the 37-year-old reality star showed off her year books and posed for photos with her classmates, and though she was having a good time, she admitted it felt "crazy" to be back at school.
She said in another clip: "We are walking down the same halls that we walked 20 years ago, this is crazy!"
