Inside Gigi Hadid and Zayn Malik's Daughter Khai’s 4th Birthday Party

Gigi Hadid and ex Zayn Malik are now proud parents to a 4-year-old, celebrating daughter Khai’s birthday with great fanfare.

Hadid, 29, offered a glimpse into the celebration via Instagram, sharing a collection of photos on Thursday, September 19. In one photo, Hadid and her daughter marveled over a pink, round cake by Carlos Bakery that read, “Happy Birthday Khai. May the FOURce Be With You.” It was topped by a realistic-looking replica of Baby Yoda from The Mandalorian. Inside, the cake was baked with rainbow layers.

The birthday bash also included an inflatable slide, a multicolored balloon arch and an arts and crafts station to paint wooden picture frames. Hadid even made a fake scroll to confirm her daughter’s “enrollment” at the fictitious Auradon Prep, the school from Disney Channel’s Descendants franchise.

“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. ,” Hadid wrote, appearing to drop a subtle reference to Malik’s Dusk Till Dawn album name. “She is curious, adventurous, loving, and oh so witty.”

Everything Gigi Hadid and Zayn Malik Have Said About Parenthood

“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,” the British singer gushed via Instagram on Thursday, sharing a photo of the father-daughter pair at the beach. “[I’m] grateful for every second I get to spend next to you, as you become the incredible person I know you already are. Four years ago, today my life changed forever and I wouldn’t be the man I am today without you.”

Hadid and Malik dated on and off for six years starting in 2015, later welcoming Khai in September 2020. After the former couple split for good one year later, they focused on building an amicable coparenting relationship.

“Coparenting is good,” Malik said during a July 2023 appearance on the “Call Her Daddy” podcast. “We have a really good relationship for Khai. She’s the, you know, the main importance. It’s going well. I think, from me [and my perspective], yeah.”
