Though we usually see her with blonde hair, the actor is a natural redhead. And look at those curls!

I always say, 'Don't ruin the ringlets!'"
The actor has been a brunette for nearly her entire career, but she's naturally blonde. Angelina reportedly said, "My natural color is dark blonde. But when I was 4 or 5, my mother dyed my hair dark brown, and she decided to keep it that way. And I stuck with that."

It wasn't until she dyed her hair dark brown that she landed major roles like Gloria in Modern Family.

The actor's natural color is dirty blonde. She dyed it brown for her iconic role in A Walk to Remember, telling Entertainment Weekly, "There was a real significance to coloring my hair. As silly as it sounds, there was a real significance in the way that people saw me, but also in the way that I carried myself and that I saw myself. It was the last little piece of the puzzle I think in terms of getting into the character." She remained a brunette for over 15 years before switching it up a few years ago.
