Gigi Hadid Wishes Bella Happy Birthday with the Cutest Baby Photo

Bella Hadid turns 21 today, but her older sister, Gigi, started celebrating a day early. Yesterday, the model, 22, wished her sibling happy birthday with an adorable throwback photo from the day Bella was born.

In the shot, a toddler-aged Gigi (decked out in a red outfit and pigtails) holds her infant little sis while their mother, Yolanda Hadid, watches over them. "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 ?)," she wrote in the caption.

Bella responded to the post with an enthusiastic comment: "OMG. I KNEW THERE WAS A REASON. LOVE U SISTER. !!!!! SO CUTE. 4EVER AND EVER. and ever. And ever and ever."

Gigi also shared a photo of a drawing she made for Bella in 2001, complete with adorable doodles and spelling.

Bella took note of that shoutout, too. She took a screen shot, posted it on her own Instagram story, and left an emotional comment. "Best friend forever. Made me cry," she wrote.

In addition to Gigi's posts, Bella was showered with loving shoutouts from her family members on her birthday. See the photos that her mom (Yolanda Hadid), dad (Mohamed Hadid), and brother (Anwar Hadid) dedicated to her on Instagram today.
