Joan Rivers, a big-mouthed and outspoken co-host of 'Fashion Police,' took aim and fired on Oscar-winner, the lovably neurotic and impeccably dressed – usually in Dior — Jennifer Lawrence.

Rivers blasted J. Law, saying she needs to be more mature, among other things. It was retaliation for J. Law saying that the comedienne's show makes it okay to judge people.

Rivers barked, "My New Year’s resolution is [ensuring] Jennifer Lawrence grows up and realizes how lucky she is and calms down."

We're not sure how J. Law isn't grateful or appreciative of her success. She comes across as very down to earth and incredibly real in the way she lets her neurosis hang out while her body is cloaked in faboosh Dior frocks.

J. Riv continued, "I love that she’s telling everyone how wrong it is to worry about retouching and body image, and meanwhile, she has been touched up more than a choir boy at the Vatican. Look at her posters. She doesn’t have a nose, she has two holes. She just has to learn, don’t talk if you’re doing it."

Hmmm, that's a suspect accusation and a really insanely low rent comment about the Catholic Church. In reality, J. Law likely has nothing to do with creating posters for her films and it's likely she does not have the final say in how they are digitally enhanced, color corrected or Photoshopped.

Lady Gaga ignited a feud with Sharon and Kelly Osbourne over a body image controversy on 'Fashion Police.' Kelly O. is also a co-host on the show, so it's not the first time the style cops have been taken to task.
