The actress, who took a sheer take on the night's theme of black gowns, spoke with ET's Nancy O'Dell on the red carpet at the Golden Globe Awards, where she opened up about the importance of women joining forces across the board to effect change.
"It's really great that women are supporting women and we have to continue to do that," the Feud star said. "Not just in our industry, not even about vying for roles. This is serious and we're all coming together, and I feel very empowered by that."
"This is a celebrating night for women," she added. "When we work together in numbers, strength is in numbers."
Zeta-Jones had heard about the movement through social media, and praised the discussion fostered by those who came forward with their stories of sexual harassment and misconduct.
"It's such a private and traumatic thing. You listen," she said. "I never pry to talk. Now the converstaion is open, it's good that everyone's talking."
"I'm supporting my ladies, and my director Ryan Murphy on Feud tonight," she said.
And chances are, Zeta-Jones could receive a nomination for next year's awards, for her role in Cocaine Godmother, a Lifetime film based on the real-life story of Griselda Blanco, a pioneering Colombian drug lord during the 1970s.
"It's a role that I've been wanitng to play for many years," Zeta-Jones said of the questionable character.
"[She's] a fascinating woman. Talk about empowerment. Not necessarily morally what we want to be as women, but she was at the top of her game in a very bad, dark man's world for many, many years," she added.
Cocaine Godmother premieres on Lifetime on Jan 20. For more on the Time's Up Movement and the Golden Globes, watch the video below.
