The pair became so close that Kris was one of the A-listers who was invited to be a guest at Jennifer and Cooke's Rhode Island wedding ceremony in October 2019.
At the time, a source told E! News that Kris, her boyfriend Corey Gamble and other guests "were picked up on boats and taken to dinner on the island."
The following year, Kris—mom to Kourtney, 43, Kim, 41, Khloe, 38, Rob, 35, Kendall, 26, Kylie, 25—jokingly adopted Jennifer into the Kardashian family. The momager called the Don't Look Up actress her "favorite daughter today" in honor of her 30th birthday.
"Thank you for your friendship, love and so much laughter my sides hurt," she wrote on Instagram in Aug. 2020. "I love you so much!!"
