Shailene Woodley was four when she kicked off her career through commercial modeling. It was only a few years before she made her screen debut in the 1999 TV movie "Replacing Dad." In 2001, she also auditioned for the starring role in "I Am Sam" opposite Sean Penn, but lost out to Dakota Fanning. Woodley stayed busy and even appeared in several episodes of the hit show "The O.C." (2003) as the young Kaitlin Cooper. Prior to landing the starring role in "The Secret Life of the American Teenager" on ABC Family, the young actress considered studying interior design at New York University.
