Gigi Hadid was among them, staying supportive of ex Zayn Malik, despite his fall out with her mother, Yolanda Hadid.
“Happy Father's Day to my sweet baba,” the part-Palestinian model, 27, wrote on a photo she shared via Instagram Stories of Malik, 29, and Khai, 21 months, whose feet you can see. Father and daughter are doing arts and crafts in the image. She added: “& to Khai’s baba!!!!”
Malik and Gigi faced issues last year when he had an alleged altercation with Yolanda, and was charged with four counts of harassment.
Gigi also shared a throwback photo on a separate story, of her own father, Mohamed Hadid, writing: "I love you!" She shared photos of herself with her dad that were added to a fan account.
Sister and fellow supermodel Bella Hadid did the same, sharing a throwback photo of her property mogul father via Instagram Stories, writing, "Happy Father's Day my baba I love you".
Gigi has been famously private since having Khai, her first child, in September 2020, largely keeping her daughter out of the spotlight and sharing only snippets of life as a mum, and never showing the face of her baby.
Bella and Gigi Hadid aren't the only models with Arab heritage — here are eight others
In an open letter posted to the star’s Instagram account last summer, she wrote: “As our baby grows up we have to realise that we can’t protect her from everything the way we wanted to and could when she was smaller.
“To the paparazzi, press and beloved fan accounts, you know we have never intentionally shared our daughter's face on social media. Our wish is that she can choose to share herself with the world when she comes of age, and that she can live as normal of a childhood as possible, without worrying about a public image that she has not chosen."
Her daughter's name is a nod to Hadid's Arab heritage, a tribute to her father's Palestinian mother, her grandmother Khairiah.
The name also has Arabic links, with Khai meaning "crowned" or "royalty" in English. Khairiah, meanwhile, means "good" and "charitable".
Both Gigi and Malik have had their daughter's name tattooed on them in Arabic since her birth.
Priyanka Chopra celebrates Nick Jonas's first Father's Day
For Nick Jonas's first Father's Day, wife Priyanka Chopra shared a photo of father and daughter to her Instagram, captioning the sweet shot: "Happy 1st Father’s Day my love. To watch you with our little girl is my greatest joy ... what an amazing day to come back home … I love you ... here’s to many more."
In the photo, you can see Jonas's legs and his shoes, which say "MM's" and "Dad", one on each foot, with baby wearing trainers that say "M" and "M".
The couple, who had their baby via surrogate on January 15, named their baby Malti, a traditional Indian name that comes from the ancient language of Sanskrit and means "fragrant flower" or "moonlight". It was typically common among older generations in India.
The child's full name is reportedly Malti Marie Chopra Jonas.
On Mother's Day, Chopra and Jonas revealed their daughter had finally come home after spending more than 100 days in a neonatal intensive care unit. Sharing the first photo of their baby girl, Chopra said the past few months had been a “roller coaster”.
“After 100-plus days in the NICU, our little girl is finally home,” she said. “Every family’s journey is unique and requires a certain level of faith, and while ours was a challenging few months, what becomes abundantly clear, in retrospect, is how precious and perfect every moment is.”
Since then, Chopra has published photos of Malti sparingly, choosing to share one image of her with Chopra's mother for her birthday.
"Happiest birthday Mama," Chopra wrote, with a photo of herself, her mother and daughter all together. "May you always smile that infectious smile of yours. You inspire me so much with your zest for life and experiences every single day! Your solo Europe tour was the best birthday celebration I’ve seen in a while. Love you to the moon and back Nani."
