We can't cope.
Zayn gave us boyfriend goals early on in the day, uploading a black and white photo of the couple to his Instagram, captioning the snap: ‘Happy birthday to my everything’.
Gigi also posted a selfie of the couple, holding a big birthday cake as her boyfriend kissed her on the cheek.
It looks like Zayn had Instagram competition, however, with a host of A-list friends and family giving the Victoria Secret model some serious social media love on her birthday.
Bella Hadid wasn’t far behind Zayn, uploading an old photo of her and her older sister.
‘Happy birthday to my best friend FOR F**king LIFE!!!!!!!!’ she captioned the snap. ‘My role model! My person. I feel so lucky every day to call you my sister. 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!!! 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. Every one 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.’
Her brother, Anwar Hadid, also posted a snap, captioning the photo: ‘Gigi! I love you so much and am so proud of how hard you work every single day, so proud to call u my sister and I hope this year brings you truth, days off, and maybe a magic pony’.
Even Gigi’s parents got involved with the Instagram birthday love, with her father, Mohamed Hadid, wishing her ‘health and joy’, while her mother, Yolanda Hadid, expressed her pride in her daughter.
‘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.’
