Gigi Hadid's Throwback With Bella Hadid Proves These Two Were Style Icons Ever Since The '90s — PHOTOS

If you're searching for something adorable to brighten your day, look no further than Gigi Hadid's latest Instagram. The supermodel shared the cutest throwback with her little sister. That's because Bella Hadid celebrated her 20th birthday on Sunday. In the photo, they're wearing matching outfits and hamming it up for the camera. I guess modeling was always in their DNA. In the caption, Gigi wrote,

Yes, you can go ahead and let out a giant "awwww!" The message is super sweet. It's no secret the Hadid sisters have one another's backs. They're always supporting each other — whether with career ventures or Bella's public battle with Lyme disease. Knowing that their bond goes way back makes this photo even better.

In the pic, they are totally owning the striped look. I also cannot handle Bella's little ponytail atop her head. It was easily the go-to style of '90s kids everywhere. Meanwhile, Gigi is rocking some braided pigtails. Seriously, they were fashion icons before they even knew it. They also look like they could pass for twins, which isn't too surprising, given their 1-year age gap.

This isn't the first time these two were sisterly goals. Remember when they danced along to High School Musical ? Yup, just like everybody else did back in middle school. (OK, I was in high school myself when the movie came out, but still, it's a classic.) Plus, they've starred in joint ad campaigns and photoshoots, like an editorial for LOVE magazine. Rather than competing, they work together.

Happy b-day to Bella! Hopefully future birthdays bring even more adorable throwbacks of these siblings. Fingers crossed.
