KOURTNEY Kardashian called out her younger sister Kim for forgetting her age in a birthday card.
The Keeping Up With The Kardashian’s star turned the mishap into a joke as she claimed that her 41st year “didn’t count.”
Kourtney, now 42, shared the hilarious mistake on her Instagram stories today, as the star showed off her birthday card.

All of the KarJenners have taken to social media today to wish Kourtney a happy birthday.
The whole famous family shared a series of throwback pictures, including old bikini shots and selfies from the three oldest girls while in their 20’s.
Kim, 40, shared an image of the family on vacation years ago, including Kris and Khloe as well.
The mom of four captioned the post: “Happy Birthday @KourtneyKardashian!!! I love finding some good throwbacks of us.
“I couldn’t be more thankful for our memories together. Love you so much and can’t wait to celebrate your birthday!”
Kourtney’s family weren’t the only ones to join in the celebration, as her boyfriend Travis Barker also took to social media to show his appreciation.
Along with several sentimental photos of the couple kissing, hugging, cuddling, and holding hands, the Blink-182 star also included a WILD video of the Poosh founder sucking on his thumb.
The drummer videotaped the intimate moment and as the camera flashed Kourtney could be heard saying: “Travis!” in the background.
The musician gushed over his lady, writing: “I F**KING LOVE YOU! 
YOU’RE A BLESSING TO THIS WORLD HAPPY BIRTHDAY @kourtneykardash,” in the caption.
Travis went all out for Kourtney’s 42nd, as he purchased an outstanding floral arrangement for her foyer.
The impressive creation consisted of a hanging installation of gardenias and a huge collection of white tulips and greenery displayed in the center of the floor.
While on a drop by visit, Kim recorded the beautiful arrangement on her Instagram stories, telling fans: “I just walked into the most gorgeous flower arrangement.
“You can smell the entire house. This is so beautiful. I’ve never seen anything like this,” she raved.
She also wished her older sister a happy birthday, adding: “Glad I made it back to smell this.”

“My entire house smells yummy.”
Travis also treated his new girlfriend to a romantic dinner at a fancy L.A. hotspot, and shared a photo of their special dessert.

The pair quickly became serious though, as the rock star already got Kourtney’s named tattooed above his nipple.
He has also hinted at their steamy sex life by sharing a shirtless photo while drumming in Hollywood, captioned: “All day I dream about sex w/ you.”
The artist tagged the mom of three in the post, confirming his feelings on the matter.
