While it's hard to imagine the brunette beauty doing anything other than gracing our screens, it seems that she fell into the spotlight after attending an audition with a friend when she was in high school (via CBS). The money was too good, so she said goodbye to her heart being set on becoming a dentist.

Had she gone that route, we likely wouldn't have her movies, roles on the silver screen or her book, Our Shoes, Our Selves. Moynahan shares her experience going through a public breakup with Brady while pregnant, and how a pair of black books helped her during those difficult days (via Yahoo Entertainment). 

The book chronicles her experience "taking her power back" after buying the pair of black boots, offering women a touchstone through similar experiences. While she didn't become the dentist she dreamed of, Moynahan boasts an impressive resume that keeps fans coming back for more.
