Another one of the most popular women on this blog is the lovely Sarah Lancaster.
I did a write up on her way back in 2008, but she seems to still be a favorite.
Sarah was born on February 12, 1980 in Overland Park, Kansas.
Of course you may know her best as Ellie Bartowski M.D., sister of Chuck Bartowski and wife of Devon "Captain Awesome" Woodcomb, M.D. on the NBC TV series "Chuck".
Like Ellie, Sarah grew up with a younger brother, but to my knowledge, her father wasn't a brilliant scientist that designed computer systems for the United States government, so the similarity stops there.
Besides Chuck, Sarah has appeared in several movies (mostly TV movies) like Sorority (1999), Smother (2008), Catch Me If You Can (2002) and Teacher's Pet (2000).
Among the many TV shows she has appeared on are Hawthorne, CSI: Crime Scene Investigation, Pacific Blue, Scrubs, Boston Public and Dharma & Greg.
