You know what your favorite stars look like now, but have you ever wondered what they were like as normal, non-famous high school students and teenagers?

Back when she went by her birth name of Amethyst Kelly, Iggy Azalea attended Mullumbimby High School in Australia, although she dropped out at age 16 to move to the United States and pursue her music career. Back then, she sported curlier hair — in comparison, now she wears stick-straight locks most of the time — and sports a totally glam look.

Hunger Games star Liam Hemsworth didn't have any of his signature scruffs when he was going to school in Australia and even had blond, curly hair as a student. (And, no, we're not even kidding.)

Same goes for Calvin Harris! Taylor Swift's ex boyfriend had dark brown hair as a youth, and looked exactly like the lead singer of a pop-punk band.
