Joan Rivers and Jennifer Lawrence are ramping up their feud again with the style maven going after 'The Hunger Games' actress in a New Year's resolution.

While the 'Fashion Police' co-host often praises the actresses talent and wardrobe choices, she's not taking kindly to Lawrence's latest comments.

It all started when the outspoken Lawrence accused the E! co-host of having a warped ideal of body image. "There's shows like the 'Fashion Police' and things like that are just showing these generations of young people to judge people based on things ... that they put values in all the things that are wrong and that it's OK to point at people and call them ugly and call them fat and they call it 'fun' and 'welcome to the real world,"  Lawrence said during a Yahoo event. The actress had more to say on the subject but, you get the idea.

Rivers, who is one of the biggest plastic-surgery advocates around, took to Twitter to retaliate. "It's funny how Jennifer Lawrence loved @E_FashionPolice during Awards Season when we were complimenting her every single week ... But now that she has a movie to promote, suddenly we're picking on all those poor, helpless actors."

Unfortunately, the verbal cat-fight did not end there.

The Oscar-winning actress was included in Barbara Walters' list of "Most Fascinating People of 2013."  In a recent interview, she told Walters that "It should be illegal to call someone 'fat' on TV." She also bashed dieting and retouching photos. It's no wonder she's a role model for so many women.

However, Rivers couldn't resist. The comedian told The New York Post's Page Six, "My New Year's resolution is [ensuring] Jennifer Lawrence grows up and realizes how lucky she is and calms down." She added, "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."

Touché, madam.
