In a preview of her interview for Barbara Walters' "10 Most Fascinating People of 2013" special, Jennifer Lawrence rails against Hollywood's narrow definition of beauty and urges an end to "fat-shaming." 

“Why is humiliating people funny? I get it, and I do it, too. We all do it,” Lawrence, 23, confessed.

"I think the media needs to take responsibility for the effect it has on our younger generation on these girls that are watching these television shows and picking up how to talk and how to be cool," she continued. "So all of the sudden being funny is making fun of the girl that's wearing an ugly dress. And the word fat! I just think it should be illegal to call somebody fat on TV. If we're regulating cigarettes and sex and cuss words because of the effect it has on our younger generation, why aren't we regulating things like calling somebody fat?"

Lawrence, who has revealed that she was ridiculed for her weight at the start of her career, recently pinpointed her anger at one television show in particular. 

"Shows like the 'Fashion Police' and things like that are just showing these generations of young people to judge people based on things [that don't matter],” she told Yahoo! CEO Marissa Mayer last month. “They put values in all the things that are wrong and [show] that it’s ok to just point at people and call them ugly and call them fat and they call it fun.”
