Mom Kim Kardashian West on Friday shared a black-and-white snapshot showing off four generations of her family: her daughter North, momager Kris Jenner and grandma Mary Jo Shannon.
The sweet picture was taken during a surprise graduation party for Kendall, 19, and Kylie, 17.
In another Tweet, Kardashian West, 34, wrote that she loves "having my grandma here to celebrate these moments!" and added that Nori is "so lucky to have her greatgrandma here!"
Plus, she's a super cool great-grandmother: Keeping Up with the Kardashians fans know Shannon, whom the Kardashian girls affectionately call "M.J.," from the hilarious episode in which she and Kris, 59, gleefully got the munchies after eating gummy bears infused with medical marijuana.
As for Nori's snack of choice? M&Ms, which her mom caught her "sneaking" between takes in the photo booth.
LOL at North sneaking m&m's between takes! pic.twitter.com/nUvycRrcvj— Kim Kardashian West (@KimKardashian) July 24, 2015
She'll have a co-conspirator soon enough: Kardashian West is expecting her second child, a son, with husband Kanye West this winter.
