Happy birthday, Shay Mitchell! The Canadian actress turns 28 today. Mitchell first got her start in modeling, but appeared in a slew of TV shows, including Degrassi: The Next Generation, before landing her first major role in Pretty Little Liars. ABC Family's hit series just finished its fifth season, and there's no indication that the young starlet is slowing down any time soon. Aside from hanging out with BFF and co-star Ashley Benson, she recently journeyed to India with ethical fashion brand Raven + Lily to help women find jobs with a sustainable income. We're wishing the fashionista a very happy birthday!
