Happy birthday, Bella Hadid!
The brunette beauty turned 21 today, which is fairly hard to believe considering all that she's accomplished by such a young age.
Not only is she one of the fashion world's "It Girls"—alongside her sister Gigi Hadid and bestie Kendall Jenner—but she's also managed to land several campaigns with major beauty brands, design apparel and shoe lines and even help spread awareness regarding Lyme disease, which she, her mother Yolanda Hadid and her younger brother Anwar all suffer from.
