Khloé was next to chime in, telling her big sister, “Happy birthday Kourt! I love you so much. You will always be the Jane to my Suzanne, the Reese’s to my Pieces, the peanut butter to my jelly.”
She continued, “I really can’t imagine my life without you. I love you so much. I think you are one of the funniest people I know when you’re actually paying attention at life. I love you, have the best time, and I hope you drink tequila until you vomit all over yourself and sleep in it, because you actually have done that a couple of times.”
Disick, who shares sons Mason, 9, and Reign, 4, and daughter Penelope, 6, with Kourtney, praised the birthday girl as a “wonderful” mum in his loving message.
Sitting beside Mason in the clip, Disick began, “Happy birthday, Mom. Happy 40th. We wish you another happy 40 to come.”
Penelope chimed in off-camera, “She looks like a kid.”
“Keep up the good work, and you look very young, P says,” said Disick, before Penelope continued, “You look like a 1-year-old.”
Disick said, “We love you so much. We appreciate everything you do and do for us. And you are a wonderful, wonderful mum. We want to see you get older and shrink and get smaller.”
At that, Mason chimed in, “I don’t want her to get shrink!”
