Gigi also shared a shot holding up her giant pink birthday cake as Zayn gave her a smooch, simply captioning the adorable photo with some heart emojis.
The Tommy Hilfiger designer was joined by her mom, Yolanda Hadid, in NYC for the special weekend. The Real Housewives alum posted a throwback photo of her daughter, writing, “Happy birthday my sweet Angel…. I pray that each day Love, Health and Happiness will come your way. I am so proud of the human being that you are and grateful to experience this journey of life with you everyday through the good and the bad. May all your dreams come true this coming year and let it be filled with joy and laughter. #HappyBirthday #MyLove #22 #ILoveYou #AlwaysAndForever.”
But it was Gigi’s sister, Bella Hadid, who really went all out on social media, posting a throwback slideshow of their childhood pics together along with a lengthy message of love.
“Happy birthday to my best friend FOR F**KING LIFE!!!!! My role model! My person. I feel so lucky every day to call you my sister,” Bella wrote. “I didn’t know anyone could be so generous, smart, funny, talented, hard working, artistic, loving, respectful AND beautiful all at the same damn time!!!”

She went on to praise her sister’s ability to help her through the hard times, saying, “You make me laugh until I pee and even when I don’t want to smile, you are just about the only person that can make me. Everyone that knows you, immediately feels the incredible energy that radiates throughout you. Thank you for always being yourself, nothing more and nothing less. You are my other half & I don’t know what I would ever do without you. I love you with all of my heart Squeegee.”
