Celebrity Yearbook Photos: Then and Now [PHOTOS]

What do Pamela Anderson, Jeremy Piven , Marilyn Manson and Denzel Washington all have in common? They were all nerds in high school!

Before they were famous and making millions of dollars each year, these celebrities also went through the process of lining up for their yearbook photos, looking much different than they are today. Actress Charlize Theron, a self-professed nerd in high school, says she was different back then. “I had nerdy glasses and when I show it to my friends, they all go hysterical!” says the actress in one interview. Although some of these stars were nerds, outcasts or geeks in high school, some of them had a natural flair for performing and being popular. According to Brad Pitt’s biography, he was involved in sports, musicals and debating while attending Kickapoo High School in Missouri – as if a real character from the Glee pool of jocks-turned-music geeks.

By the looks of these photos, it’s hard to imagine that they have become multi-millionaires with their talents. These photos are compiled by gossip website Celebuzz from the yearbooks of these famous personalities.
