(contactmusic.com) - Oscar winner Reese Witherspoon has branded Britney Spears, Lindsay Lohan and Paris Hilton bad role models for women. The Walk The Line actress is angry the "sad and very strange" behaviour of the hellraising trio undoes the work of women from previous generations who fought against a male-dominated society. She says, "We don't need to keep reading about female celebrities who are out there posing all the time and craving attention and exploiting the sex symbol stereotype. "My mother and grandmother fought incredibly hard against a male establishment to become high achievers in their lives, and I think women should be able to be sexy and smart and successful - without being silly and aimless."
