While all eyes are normally on the A-listers during awards show red carpets, that changed on Sunday. As part of the "Time's Up" initiative, aiming to bring awareness to gender inequality and sexual harassment, celebrities used the ceremony to highlight the movement, as well as their plus one's -- some of the brightest, most powerful women in the industry, and the country.
"We wear black for so many reasons," Longoria explained to ET. "We wear black to say, 'Time's up' on the imbalance of power and abuse of power. We wear black for all the women and whistleblowers that came forward: Asia Argento, Rosanna Arquette, Ashley Judd, Olivia Munn, Gabrielle Union, Terry Crews."
"Anthony Rapp. People who were so brave to tell their stories first," added Witherspoon. "And we're standing here because of the courage they had and also, women in all industries and men in all industries that are standing up and saying, 'Enough' with discrimination and harassment and abuse. We deserve equality and time is up."
Amy Poehler and Saru Jayaraman
The comedian took the author, advocate and president and co-founder of Restaurant Opportunities Centers United as her date to the awards show this year. Their smiles say it all!
Emma Stone and Billie Jean King
Stone joked to ET on the carpet that she was "banging" on the tennis player's door in hopes that she would answer and attend the awards show with her. "Emma texted me and said, 'Will you be my date?' and I said, 'Yes,'" Jean revealed. "We're here in solidarity, anyway, for activist groups. We met with activists yesterday, it was an amazing day and I hope everybody goes to timesupnow.com and they'll learn all about it. We're here to really support the people who have been silenced by abuse and harassment."
"I'm just fortunate that Emma, an icon in my mind anyway, in everyone's mind I hope ... she did such a great job in Battle of the Sexes movie, and it's one of the highlights of my life," she continued. "To get to know her as a human being has been just so rewarding, and it's been great that, I think everybody did such a great job in Battle of the Sexes."
Susan Sarandon and Rosa Clemente
During their joint interview with ET, Sarandon handed the mic to Clemente, an organizer, political commentator and independent journalist, who recently returned from Puerto Rico.
"I'm a Bronx-born, hip-hop baby, Afro Latina woman and I'm Puerto Rican, so of course, when the hurricane hit, it was terrible," Clemente said. "And unfortunately, Puerto Rico is still in a lot of crisis. Over half the island still does not have power. Ninety percent of the people don't have drinkable water."
"We obviously worry about women, particularly when crisis has happened," she added. "In the best of times, women are not safe. But when a crisis happens, they are not safe twenty times over. I still have family there, and unfortunately, my aunt recently passed away because of medical neglect -- because there was no power."
Emma Watson and Marai Larasi
The Beauty and the Beast star brought along the executive director of Imkaan, a black feminist network organization based in the United Kingdom that tackles violence against women and girls.
"I have learned so much working with and through my friendship with Marai," Watson tells ET. "We're just really excited to be here tonight because it's... this is just unprecedented. This show of solidarity and unity with women across industries, across communities."
"This is an infection point, "she continued. "We're not going back. I think that there's just been this incredible breakthrough on this and women are talking to one another and we're forming communities and we feel so strong together."
Watson added that when she first heard about how others from the "Time's Up" movement would be taking on the Globes carpet, she knew right away she wanted Larasi as her date.
"I was like, 'Whoa, if I could do the red carpet with Marai, then it would be amazing and way more fun than it normally is," Watson explained. "And also, she really knows what she's talking about. She's been doing this work for over two decades, and to hear her voice in this space, on this night... it's [amazing]."
Natalie Portman and America Ferrera
"It's very fun to get to be on the red carpet together," Portman gushed while chatting with ET. "There are several women who turned into several hundred very quickly, and we've all been working together to try and take these experiences that so many of us have had and turn it into meaningful change. To transform that pain into something that's going to make a new day and celebrate together.
"Natalie is bringing me along as her date, but we have been working with hundreds of other women in our industry for the last few months," added Ferrera. "Hoping this action of solidarity would come together in the beautiful way that it is. We're standing here together to say, 'Times up,' and we're ready for women to be safe and equal in the workplace and in their lives."
"It's just about gathering our community," she continued. "In so many instances, we're often one of very few women on set, or one of the very few women producing, or writing or directing. And we know of each other, but we don't really get to be in the same rooms because we're isolated in a lot of ways. It started with us getting together and talking."
Michelle Williams and Tarana Burke
Williams told ET on the carpet that she's "full of optimism and enthusiasm" that together we can all make a permanent change.
"I thought that I would have to raise my daughter to learn how to protect herself and defend herself against the world, and what I've realized is that it's actually possible," the actress shared. "I believe it with all my heart that because of the work of women like Tarana that we hand our daughters a different world."
Added Burke, "I started something in my community that grew larger to help women who look like me, and it kept growing and it kept growing and eventually we got to this moment. But I could never have dreamed that it would get here, certainly."
Laura Dern and Monica Ramirez
The Big Little Lies star tells ET that she reached out Ramirez when she read "her extraordinary letter of solidarity in Time magazine," dedicated to the women in our industry, from the women in the industry.
"I represent the 700,000 women who pick and plant the food that we eat every day, and farmer women organizing against workplace sexual violence for decades," Ramirez explained of her work. "When we wrote our letter, we wanted to send a clear message that women in the entertainment industry were not alone and that we stand with them and all who were experiencing this problem across all industries and sectors."
Ava DuVernay and Lena Waithe
"We're just feeling charged," DuVernay said of how she and her date were feeling on Sunday. "There's a new energy in the air. I think it's something to embrace. I think so."
"Symbolism is important," she added. "When I was directing Thirteen and Selma, I did a lot of study about movements and symbolism and how to get people aware of these issues and this is what this is. This is not gonna solve a problem, but it is an international platform to ring a bell about what's going on. So, I'm all for it."
Jessica Chastain and Octavia Spencer
"We go way back. We're sisters," Chastain said of her friendship with Spencer -- the two starred together in 2011's The Help. "Solidarity. We're here for the Time's Up movement, our defense fund that will help protect men and women coming forward to fight against any sexual harassment, sexual assault and the fallout from coming forward."
"What pushes me is the courage that women and men have to be the first one to tell their story," she continued. "That's no small feat to do. I'm just blown away by the strength that that takes. I want to do whatever I can to amplify their voices and support them."
Spencer echoed those sentiments, telling ET, "I can tell you that Reese Witherspoon, Kerry Washington, America Ferrera, Jessica Chastain... I mean, they have been wonderful leaders for me."
"I'm just excited to be a part of this," she added, "because time's up and this time has come."
