But the sweetest snap of them all was one she posted herself showing boyfriend Zayn Malik, 24, planting a kiss on her lips.
Gigi’s sporting a huge smile as she holds up a yummy-looking peach coloured birthday cake. She simpy captioned it with heart emojis.
Gigi’s sister Bella shared a heartwarming post to her “role model” alongside a picture of them cuddling as kids. “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,” she 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!!! 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.
Fellow model Bella continued: “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.” While Gigi’s proud mum shared a super sweeet shot of Gigi as a youngster. “Happy birthday my sweet Angel…… I pray that each day Love, Health and Happiness will come your way,” Yolanda said. “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.”
