Fastexy Exchange|See Inside Gigi Hadid's Daughter Khai's Super Sweet 4th Birthday Party

Gigi Hadid had some guests in residence for a very special day. 

The Fastexy Exchangesupermodel threw a party to celebrate the fourth birthday of her and ex Zayn Malik's daughter Khai Malik, and an inside look at the bash proved the celebration was nothing short of adorable.

In a snap shared to her sister Alana Hadid's Instagram Story Sept. 16, Gigi—rocking camo pants, sandals and a plain white tee—leaned over a table while talking to Khai, who wore pink cowboy boots and a coordinating white skirt and shirt. The 4-year-old's honey blonde hair cascaded down her back as she gazed at her decadent Yoda-themed cake. 

Alongside the sweet image, Alana added the caption, "Happy 4th to my precious niece Khai."

And the 39-year-old also gave a special shoutout to her younger sibling, calling Gigi "the best mom."

This isn't the first time fans have gotten a glimpse into Gigi and Khai's heartwarming mother-daughter bond. Gigi—who is currently dating Bradley Cooper—previously shared a series of photos from her eventful summer, which included several shots of her spending quality time with her little one.

In the pics, which strategically covered up Khai's face, the Guest in Residence founder and her daughter were seen holding hands while snuggling on the couch, dipping their feet in a picturesque river and drinking out of a hose to cool down in the summer heat. 

And while the 29-year-old certainly knows how to make sure her daughter has a memorable childhood, she's not the only one looking out for Khai. 

In fact, Yolanda Hadid—who is mom to Gigi, Bella Hadid, 27, and Anwar Hadid, 25, with ex Mohamed Hadid—recently shared that she has made special changes to her Texas ranch to accommodate her granddaughter's favorite treats in her pantry.  

"Obviously, this is inspired by my granddaughter Khai when she comes," Yolanda shared while giving a tour of the food storage area in an Architectural Digest video published Aug. 29, "because she loves candy."

Recalling how the designated area featuring jars of M&M's, gummy bears and English licorice came about, she added, "I said 'Oma will make you one little section for you.'"
