Kris Jenner is bringing back the art of letter writing after writing a 20-page message to daughter Kim Kardashian for her 40th birthday.

“I always thought I’d write a letter to my kids, but you know, it really takes a lot of time because I write really long letters,” said the 65-year-old Keeping Up with the Kardashians star at At Home with Linda on Tuesday & Drew Scott Podcast. “And I hadn’t written one for a long time.”

“When it was Kim’s birthday last year, I sat down and wrote her a really nice letter about how I felt for her,” said Kris. “And I think it was about 20 pages or something like that.”

Kris noted that it had taken “a few hours” and that she had already written letters for daughters Kourtney Kardashian, Kendall, and Kylie Jenner. Their children, Rob and Khloé Kardashian, are next. “Anyway, I’m almost done with the six letters,” said Kris.

“But I just started giving births and said this was one of the six greatest days of my life and some kind of place for them in my heart,” she explained. “And then I came across the different things in life that meant so much to me and the special moments that I will never forget. So that means everything to me.”

Kris recommended on the podcast that everyone write letters to loved ones while they still can. “If I were to give anyone advice it would be to write a letter to a child or a parent or someone who really meant so much in your life that you just have to say that for them to have it,” said she said.

The self-proclaimed “Momager” is preparing to say goodbye to KUWTK as the family will broadcast their last episode this summer after 14 years and 20 seasons. The final will be followed by a reunion which, according to host Andy Cohen, will cover “everything”.

“It’s been one of the best family times,” Kris recently told WSJ. Magazine for filming the farewell season. “We always go in so many different directions and we all have 20 jobs. But that really gave us a chance to reconcile and appreciate the time we spent together knowing it was our final season. “
