The Hunger Games star Jennifer Lawrence has both a great sense of humor — and a very good sense of self.

A source close to the actress told me Sunday that the Oscar nominee had a sarcastic reaction to some of the critics of her mega-hit movie who basically claimed she was too chubby-looking to convincingly play Katniss Everdeen in the blockbuster, based on Suzanne Collins’ best-selling novel.

“Jennifer told me, ‘This is hilarious. First, people say how so many actresses in Hollywood look anorexic, and now they are criticizing me for looking normal,’” the source recalled. The actress reportedly added that overly thin body images “are too often adopted by young girls and women — thanks to what they are constantly being shown as being attractive.”

Another point supposedly made by Lawrence was that nothing was written about her two main co-stars — Josh Hutcherson and Liam Hemsworth — who both also play residents of the film’s fictional District 12, where people are constantly facing starving conditions.

While most critics raved about the film and Lawrence’s performance, it was comments from the Hollywood Reporter’s Todd McCarthy (about the actress’ “lingering baby fat”), Salon’s Andrew O’Hehir (“well-fed” body) and Hollywood Elsewhere’s Jeffrey Wells (calling Lawrence a “big-boned lady”) that have unleashed a torrent of furious responses from the legions of loyal Hunger Games fans.
