After kicking off the day by sharing that she and her little girl had enjoyed some cake for breakfast and taken a trip to the park, the supermodel, 29, later posted a carousel of images in honor of her daughter's 4th birthday on Thursday, Sept. 19 -- revealing that Khai had a pretty special party to celebrate her big day.
Among the snaps, Hadid shared a cute photo that showed the mother-daughter duo standing next to a table with an impressive Baby Yoda cake, complete with a message reading, "May the FOURce be with you."
In the pic, Khai wore a white T-shirt and shorts with pink cowboy boots and had cute braids at the front of her long brown hair, while her mom stood close by, smiling in a white sleeveless T-shirt and cargo pants.
The next photo showed a close-up of the cake, which featured a "Happy birthday Khai" message and was topped with a Baby Yoda character that appeared to have been made from icing.
Other snaps in Hadid's carousel showed a garden set up featuring balloon arches, an inflatable slide and a number "4" balloon, a pic of a table covered in crafting materials with people sitting at it, a snap of what appeared to be Khai adding sprinkles to a cup of ice-cream and a Baby Yoda-themed "Happy Birthday Khai" sign that had been strung up behind the table with her cake on it.
The birthday girl's celebrations also included riding on a horse that had rainbow colors in its mane and tail, receiving a scroll inviting her to join Auradon Prep (the fictional school from Disney's Descendants), having her hair braided with red ribbon, playing in a garden and more.
"Our girl is 4 today and we celebrated all week!!! She loves animals (fantastical ones too), music, baby yoda, all things nature & bugs, Descendants, anything squishy or miniature, and if possible- will be in the water from dawn til dusk. 🐬," the supermodel began the caption of her post.
She continued, "She is curious, adventurous, loving, and oh so witty ⚡️⚡️ Khai- it is my life's greatest joy and pride to be your mama!!!! Thank you for the four best years of my life- you remind me to live life to the fullest every day, in the most simple & beautiful ways. Your possibilities are endless, my sweetest love !!!! 🦄🪱🧁🪐🥑🧜♀️🐣🎸🏖️ YODA BEST 💚."
Hadid shares her daughter with ex, Zayn Malik and the singer had his own special message for Khai on Sept. 19.
"Happy birthday to the most important person in my life, I love you more than words allow me to express, beyond proud to call you my daughter.. grateful for every second I get to spend next to you, as you become the incredible person I know you already are," he wrote alongside a photograph of himself holding his daughter as they stood facing away from the camera on a beach.
"Four years ago today my life changed forever and I wouldn't be the man I am today without you," Malik, 31, concluded the heartfelt post.
