The eldest Hadid sib, who’s just shy of a year-and-a-half older than Bella, shared the ultimate throwback on Sunday when she dropped a photo from the day of Bella’s birth. In the adorable shot, Lil’ Gigi wears a red sweatshirt and matching hair ties, her blonde hair pulled into the sweetest pigtails while she cradles newborn baby Bella. At the edge of the photo, Mama Yolanda is visible with her arms outstretched as she gently reaches for both of her daughters. gigihadid/Instagram In addition to the aw-worthy pic, Gigi followed up with this caption: “TOMORROW WILL BE 21 YEARS SINCE I MET MY FOREVER BESTIE @bellahadid ❤ (me wearing all red on your actual day of birth is MAJOR and possibly the reason it's your favorite color 😜).” Hmm … we think Gigi might be onto something with this—Bella does love red. Happy 21st, Bella! We’re sure you’ll do the milestone justice.
