Gigi Hadid was joined by Bella Hadid and Blake Lively to celebrate her daughter Khai’s 3rd birthday at an adorable slime-themed party.

The supermodel — who shares her only child with ex-boyfriend Zayn Malik — treated the little one to an ooey-gooey birthday bash at New York City’s interactive slime museum, Sloomoo Institute, on Saturday afternoon.

Page Six has learned the party was hosted inside a private room at the venue, which is located through a secret entrance in the Slime Kitchen.

“Attendees were able to immerse themselves in the experiential play creating their own custom slimes and even getting slimed at ‘Sloomoo Falls,’” a source told us.

Gigi, 28, wore a simple white tee with a hot pink skirt, while her sister Bella, 26, layered an oversized button-up shirt over a white top and trousers.

The “Next in Fashion” host’s dad, Mohamed Hadid, was also there to celebrate his granddaughter along with Gigi and Bella’s 24-year-old brother, Anwar Hadid.

The family members posed for cute photos together while Gigi held her custom blue slime in hand.

It’s unclear whether Malik attended the celebration, and the supermodel’s rep did not immediately respond to Page Six’s request for comment.

The Guest in Residence founder and the former One Direction member, 30, have been co-parenting their daughter following their contentious breakup in October 2021.

The duo split after Gigi’s mom, Yolanda Hadid, accused Malik of striking her during an altercation, though the singer vehemently denied the allegation.

He was sentenced to nearly a year of probation as well as domestic violence and anger management programs.

Gigi stayed mum about the family feud and shared that their daughter was her only priority.

“Gigi is solely focused on the best for Khai. She asks for privacy during this time,” her rep told People in a statement at the time.

In March, she made a rare comment about her and Malik’s co-parenting situation, telling the Times of London that she plans her work schedule around when Khai “is with her dad.”

The runway star added, “That she can be with both parents makes me very happy.”

Meanwhile, Malik touched on being a father during a July interview with Alex Cooper on the “Call Her Daddy” podcast.

“Since I’ve had my daughter, the main thing in my mind is trying to be a good example to her,” he said during his first interview in six years.

“That’s why I’m even doing this interview, you know?” he continued. “I used to get a lot of anxiety around having a conversation like this. And I want her to be able to look at me and be like, ‘Yo, my dad’s doing this.’”

The model and the “Pillowtalk” artist welcomed their baby girl in September 2020 after dating on and off for almost six years.

Following their split, Gigi has been romantically linked to Leonardo DiCaprio since September 2022. They were most recently spotted together in the Hamptons in July.
