(Web Desk) - Kourtney Kardashian Barker isn't letting feuds stop her from celebrating sister Kim Kardashian on her birthday!
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”.
Despite their issues on the show, Kourtney continued to show more love to Kim on her birthday as she posted follow-up throwback snaps of the pair.
In one photo, the pair posed as children in matching outfits with their initials "K" on their sweaters in a Polaroid marked "Halloween ‘87."
“Twinning since the beginning @kimkardashian,” Kourtney wrote in her caption.
The pair were then seen in another snap posing together in matching black long dresses. Kourtney added, “And always @kimkardashian."
Other photos shared included one of Kourtney and Kim dressed in matching white lingerie and wings as Victoria’s Secret Angels for Halloween, and one of the pair dressed up as a clown and Snow White as children for the annual holiday.
Among the rest of the family to give birthday tributes to Kim were mom Kris Jenner and sisters Khloé Kardashian and Kylie Jenner.
