Gigi Hadid has taken to Instagram to wish younger sister Bella 'happy birthday' ahead of her 21st birthday, on October 9.
In Hadid family tradition the milestone has been marked with a photo from their childhood. "TOMORROW WILL BE 21 YEARS SINCE I MET MY FOREVER BESTIE," Gigi wrote alongside the family snap.
"Me wearing all red on your actual day of birth is MAJOR and possibly the reason it's your favorite colour," the 22-year-old continued.
Nowadays, Gigi and Bella are two of the most in-demand models on the scene, but before the catwalks, campaigns, and covers, the Hadid sisters were just camera-shy angelic toddlers. In fact, the Bella once told mum Yolanda Hadid, “no more pictures mommy,” which is ironic considering her current day job.
