"This whole experience is just overwhelming and unbelievable, because I'm literally just a girl from Nashville who had a big dream," Reese said during her acceptance speech.

Big dreams, indeed! Reese is the first female to win the award since Julia Roberts in 2007, preceded by Nicole Kidman in 2003, Jodie Foster in 1999, and Bette Midler in 1987.
