An Academy Award-winning actress has something against the "F-word" — not the four-letter one, but a three-letter one: "fat."

Jennifer Lawrence, who won an Oscar this year for her lead role in "Silver Linings Playbook," told Barbara Walters during an appearance on the ABC News special “Barbara Walters: The 10 Most Fascinating People of 2013” that it “should be illegal to call somebody fat on TV,” reports People magazine.

Lawrence, the star of “The Hunger Games” films, recently got into a battle with Joan Rivers for teaching young people “the wrong values,” the story says.

Lawrence told Walters, “Why is humiliating people funny?,” referring to catty comments from red-carpet critics such as Rivers, the story says.

"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," Lawrence said. "So all of a sudden being funny is making fun of a girl that’s wearing an ugly dress."

She added, "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 people fat?"
