The outrageous new trailer for the upcoming comedy 'Young Adult' features prim and proper Charlize Theron as you've never seen her before. 

As an aging party girl who returns to her hometown to win back her high school sweetheart, Theron's character drinks and curses up a storm. The second film from the 'Juno' team of director Jason Reitman and screenwriter Diablo Cody, 'Young Adult' looks to be the edgy, indie answer to 'Bad Teacher.'

Check out Charlize Theron's potty mouth in the trailer below. 'Young Adult' opens on December 9.
