Kim Kardashian is celebrating her birthday girl!

On Wednesday, Jan. 15, the Skims founder, 44, marked her daughter Chicago’s 7th birthday by penning a sweet tribute to her on Instagram.

“My twin soul baby girl Chi turns 7 today!” Kardashian wrote alongside a carousel of selfies of the mother and daughter duo. “You are the cutest Hello Kitty loving, full of wonder sweet girl who loves your friends and family so much! We all love you so much! Happy Birthday my Chi Chi.”

The photos see The Kardashians star — who shares Chicago, daughter North, 11, son Saint, 9, son Psalm, 5, with ex-husband Kanye West, 47 — stick her tongue out and pout her lips as she posed for photos with the birthday girl.

Kardashian then reposted a fan page’s collage of photos of herself and Chicago on her Instagram Stories.

Grandma Kris Jenner also expressed her love for Chicago on her birthday by writing an emotional message.

“Happy birthday to our sweet Chi Chi! I can’t believe you are seven!!!,” her caption read alongside a carousel of photos of the little girl. “You are such a shining light in all of our lives! You are so caring, kind, and so full of love.”

“I’m so proud of the smart, creative, and thoughtful girl you are,” the momager continued. “You’re the most amazing granddaughter, daughter, sister, cousin and friend, and we are all so blessed to have you. I love you more than words can say, my angel pie!”

The images included a snap from Chicago’s Bratz-themed birthday party last year, as well as photos of herself with her mom, grandmother, aunt Khloé Kardashian and cousins.
