Jennifer Aniston Goes Brunette!

Jennifer Aniston, 42, goes brunette for her upcoming comedy Horrible Bosses. Costarring Colin Farrell, Kevin Spacey and Jason Bateman, Horrible Bosses is more than a hair-color switchup for Aniston. She plays a dentist who sexually harasses a male employee (Charlie Day) and, according to one source, Aniston bares her breasts in at least one scene. She shot a topless scene, but producers aren't sure if they'll use it.
