The youngest Keeping Up With The Kardashians stars chose a very flashy way to declare their love for their momager: a massive display of balloons spelling out I Love Mum!
Lucky Kris has such a big entrance hall to fit all those balloons!
Kris was clearly overwhelmed, sharing a photo of her gift alongside the caption: "I love you both so much!! I kind of have the best kids in the world."
Kendall reposted the image to her own Instagram alongside the simple message, "Cause she's a cool mum", while Kylie's message read: "HAPPY MOTHER'S DAY MUM! We love you!!!!"
They weren't the only kids of Kris to be sending her well-wishes. The rest of the family - apart from Rob - all posted sweet messages to their own social media accounts:
"Everything I am I owe it all to you mum! Everything I will teach my daughter you taught me first! Thank you mum for being there for me & loving me unconditionally! I love you so much!!"
"Mothers love is the fuel that enables a normal human being to do the impossible." I love you mama!!!!!"
"Happy Mother's Day to my mommy who gave me the best childhood in the world and inspires me to be the absolute best mother I can be for my children."
