Kim Kardashian celebrated turning 43 on Saturday

Kourtney Kardashian Barker isn't letting feuds stop her from celebrating sister Kim Kardashian on her birthday!

On Saturday, the Poosh founder, 44, spoke about the various feuds she’s had with Kim over the years in a birthday tribute to the star, who turned 43.

“Happy happy birthday to my first sister,” Kourtney wrote as she posted a throwback photo of herself and Kim on her Instagram Story.

“Thank you for all those years of bossing you around and you actually listening to all of my crazy ideas. People think the fights they’ve seen on tv are bad if only they got to witness the hair pulling, nail digging ones from early high school," she continued.

“The joys of sisterhood," Kourtney jokingly added. "I love you deeply forever and always. May God bless this year with love and happiness and abundant joy ❤️.”

Kourtney is involved in an ongoing feud with Kim on the latest season of The Kardashians.

Their fighting began after the pair got into an argument over edits seen from the previous season of the show, relating to their feud over Kim's partnership with Dolce and Gabbana after they designed Kourtney's wedding dress.
