Jennifer Lawrence backs up E! host Catt Sadler after she quit over pay gap dispute

Sadler's male co-host was reportedly making double her salary.

Jennifer Lawrence is cheering on Catt Sadler for sharing the real reason why she left her job as a host of E! News after 12 years.

"Thank you Catt for sharing your story," Lawrence, 27, wrote on Facebook on Wednesday (Dec. 20), with a link to Sadler's website post from the night before.

In a lengthy essay Catt opened up about her decision to quit her beloved celeb anchor gig after discovering her male co-host was making almost twice her pay and the company wasn't willing to try and match it.

"I have two decades experience in broadcasting and started at the network the very same year as my close friend and colleague that I adore," Sadler wrote on The Catt Walk Tuesday, apparently referencing her E! colleague, Jason Kennedy. "But how can I operate with integrity and stay on at E if they're not willing to pay me the same as him? Or at least come close? How can I accept an offer that shows they do not value my contributions and paralleled dedication all these years? How can I not echo the actions of my heroes and stand for what is right no matter what the cost? How can I remain silent when my rights under the law have been violated?"

In the past Jennifer Lawrence has been outspoken about the pay gap disparity between men and women, especially in Hollywood. Through the Sony hack the Oscar-winner discovered she was often being paid far less than her male co-stars like Bradley Cooper, Christian Bale, and Jeremy Renner.

In October 2015 Lawrence penned a powerful essay for Lena Dunham's Lenny Letter on the topic. In it the 27-year-old opened up about what often stopped her from asking what she felt she was actually worth.

"I didn't want to seem 'difficult' or 'spoiled,'" she wrote. "That seemed like a fine idea, until I saw the payroll on the Internet and realized every man I was working with definitely didn't worry about being 'difficult' or 'spoiled.'"

Jen continued: "I'm over trying to find the 'adorable' way to state my opinion and still be likable!" she continued. "F—K that. I don't think I've ever worked for a man in charge who spent time contemplating what angle he should use to have his voice heard. It's just heard."

Jessica Chastain also made it public whose side she was on when it came to Catt vs. E! On Wednesday (Dec. 20) the Oscar-winner tweeted: "WOW this is so disappointing. When are companies like @e_entertainment going to understand that women should be paid fairly. 1/2 of her male counterpart is not appropriate."

A very similar network dispute played out here in Australia when longtime TODAY host Lisa Wilkinson left Channel Nine after the company refused to match her former co-host Karl Stefanovic's three year deal worth $9 million.

Of the veteran broadcaster's resignation, Nine said is a statement it was "unable to meet the expectations of Lisa Wilkinson and her manager on a contract renewal for a further period."
