Days after Jennifer Lawrence penned an essay bemoaning the gender pay gap, her frequent collaborator Bradley Cooper urged his fellow actors to be "more transparent" about their salaries, so their female co-stars could be clear about they're worth to the movie studios.
Now a new Care2 petition has been launched to encourage Clooney, 54, to follow Cooper's lead and reveal his salary information.
Almost 10,000 people have already signed the petition, which was written by feminist Julie Rodriguez.
"While it's easy to dismiss the concerns of professionals like Jennifer Lawrence as coming from a place of privilege most of us will never know, the fact is that sexism in Hollywood reflects sexism within our culture in general," she said.
