Who Is Gigi Hadid?

Lately, it seems like we can't go a day without something huge happening for the seriously stunning Gigi Hadid. At just 20 years old, the It girl has already managed to take Fashion Month by storm, land some pretty amazing campaigns (Tom Ford, anyone?), and pose alongside her crew in high-fashion editorials.

But it's not just her professional style that has caught our eye. Her killer street style plus her position in the new brat pack make her one to watch. And if that's not enough to buzz about, Gigi's already modeled in the pages of Vogue and rocked sexy swimwear for Sport's Illustrated — how's that for versatility?

So as Gigi turns the big 2-0 today, let's toast to all of her success thus far — before she gives us even more to talk about. Now read on to learn the reasons this golden girl has captured our attention.
