"Wondering why we wear black?!?!?! Because we stand with YOU," she tweeted. "We stand in solidarity. Together we can end harassment, discrimination & abuse. And create safety, inclusion, equity & parity! FOR ALL PEOPLE. ACROSS ALL INDUSTRIES."
"Wearing black today in solidarity with the men and women asking for respect and equality across industry lines. Let's bring a stop to sexual harassment in the workplace. Join us in wearing black and saying times up," Mark Ruffalo tweeted.
Debra Messing was also wearing all black and during her interview with E! red carpet correspondent Giuliana Rancic, the "Will & Grace" star called out the network for the "massive disparity in pay" Catt Sadler said she earned in comparison to her male co-host, leading to her quitting the job.
"I am wearing black to thank and honor all of the brave whistleblowers who came forward," Messing said. "Time is up. We want diversity, we want gender parity, we want equal pay. I was so shocked that E! doesn't believe in paying their female cohosts the same as their male co-hosts. I miss Catt Sadler. We stand with her and that's something that could change tomorrow. We want people to start having the conversation that women are just as valuable as men."
