Amber Rose, Joe Manganiello, and More Stars Who Used to Be Total Nerds

Rashida Jones was an over-achiever.

"In high school I never drank, I never smoked, I never smoked weed," she told Playboy. "I was president of the varsity club and was on the math team and then student government. I was in every activity."

Joe Manganiello was bullied.

"I had big ears that stuck out," he said. "My parents, in order to hide my ears, then grew my hair out over my ears, and as a result, the kids called me 'fro-y joey.' And I would get punched and beat up at school and come home really hurt."

Margot Robbie was a Potter nerd.

"Literally, the most embarrassing photo of my whole life," she said about the above photo. "I'm clearly really enjoying myself reading Harry Potter. I have braces, which I had for two years. I was really into slicking my hair back, God knows why. And I'm wearing glasses, which I didn't actually need."

Amber Rose was an "ugly duckling."

"Hey kids if u feel like an ugly duckling don't fret," she wrote, "just look at this picture of me as a kid and know there's hope for all of us Lol."

Jennifer Garner was unpopular.

"I was a real nerd. I wasn’t the popular one. I was one of those girls on the edge of the group," she told The Mirror. “I never wore the right clothes and I had a kind of natural geekiness. I was in the school band and I think that has a bit of a stigma at the age of 13. If you’d asked me what I wanted to be, I would have said something like a librarian.”

Vin Diesel was really into Dungeons and Dragons.

"I played very, very religiously. It was my favorite thing to do," he said. "I had a character named Melkor…I miss Melkor."

Kelly Osbourne looked like this.

"#ThrowbackThursday Me in high school! I was such a dork!" she tweeted.

Tina Fey was a late bloomer.

"I probably didn't see a penis until my late '20s," she said. "And that was in a medical journal."

Cristin Milioti was teased for her haircuts.

"I showed up like, 'What's up, guys! I'm ready to hang!' And they were not nice," she said. "I remember one time I was shoved into a locker."

Eva Longoria was a band geek.

"I was [the] drum major for the band," she said. "I had a perm! But who didn't in the '90s?"

Angie Harmon wore braces.

"Um… This happened. You're welcome," she wrote.
