Gigi Hadid is marking her first birthday as a new mother.
The supermodel, who welcomed daughter Khai in September, celebrates her 26th birthday on April 23.
The star, who is of Palestinian and Dutch descent, was born in Los Angeles to former model Yolanda Hadid and real-estate mogul Mohamed Hadid.
And, to mark his daughter's big day, Mohamed Hadid decided to share a number of facts about the catwalk favourite.
Taking to Instagram, the Palestinian-Jordanian developer shared birthday wishes for "the sweetest baby you are", and paid tribute to his new granddaughter, adding: "You made sweet baby Khai."
Gigi Hadid and her long-term boyfriend, former One Direction singer Zayn Malik, welcomed their firstborn, Khai, last autumn.
Calling her a "model citizen", Mohamed Hadid also revealed he would share 20 things "you did not know" about his daughter to mark her birthday week.
He initially shared seven facts in a post, including the fact that the model starred in her first campaign, for Guess, when she was Khai's age.
Mohamed Hadid also described his daughter as "self-made", adding: "She never took a single dollar from her parents."
Gigi Hadid was also accepted on to New York University's forensic criminal psychology degree after graduating high school, although deferred entry to pursue modelling.
"She has the highest number of Vogue magazine covers worldwide, around 50," Mohamed Hadid continued.
"She was an accomplished equestrian, junior Olympic contender and [won] hundreds of first place and national championships.. [she] still rides today."
The remaining 13 facts are yet to be shared.
Gigi Hadid has previously spoken extensively about her love for horse-riding, sharing clips from her competition days on social media.
She also revealed in a 2018 Instagram Live that while she was always fascinated by criminal psychology, she wasn't sure she would have ended up working in the industry.
"Although I'm so intrigued by that field of work, I think that if I would have had a career in that I would've still ended up working in something creative instead," she told fans.
"Even after I'm done modelling I think I'll always be a part of a creative process somehow."
