Rock -- who helped Jones get her job at Saturday Night Live -- called out Jennifer Lawrence's essay in Lena Dunham's Lenny newsletter, where she admitted feelings of self-loathing after it was revealed that she and Amy Adams were paid less than their male American Hustle co-stars.
"Black women have the hardest gig in show business," Rock said. "You hear Jennifer Lawrence complaining about getting paid less because she's a woman -- if she was black, she'd really have something to complain about."
Lawrence's essay led to several other celebrities speaking out about the pay gap in Hollywood, including her recurring co-star Bradley Cooper. "There's a double standard in the whole world, yeah, for sure. This is just one aspect," Cooper told ET. "Anytime there's a place where a voice can come out and be outspoken -- something Sienna did, or Jennifer -- that's great. ... I think it is making a difference."
