Olivia Wilde hasn't always been a brunette beauty, starring alongside big-name stars like Harrison Ford and Daniel Craig.
Long before she was hitting the big screen in Jon Favreau's film "Cowboys & Aliens" and walking the red carpet with co-star cutie Ryan Reynolds, Wilde was holding her own on the small-screen.
Over the years she's bounced back and forth between TV and movies, and hair colors for that matter, most recently playing 'Thirteen' in the Fox series "House" and starring in "The Change Up" with Reynolds and Jason Bateman.
Here is a photo of a blonde Wilde from the film "The Girl Next Door" in 2004. To see photos of Wilde's roles through the years, visit Snakkle.com.
