Time's Up, announced last Monday, is an initiative created by several hundred actresses and female agents, writers, directors and entertainment executives to fight sexual misconduct across the country.
The model definitely had heads turning when she showed up in a pale pink, glittery gown on the red carpet.
"We were up against the holidays", she added.
She said that she believes change is long overdue, and her decision to wear red doesn't mean that she's against the movement.
Janney added, "I'm wearing black to stand with every man and women out here in Hollywood to stand-up for people, mostly women, who have been sexually abused, assaulted or harassed and made them feel unsafe at workplace and who have been held back due to their sex".
"Well I think that people are aware, now, of a power imbalance".
Many other empowering voices took the stage, all in black.
"We support gender equity and equal pay and we hope that E! follows that lead with Catt as well", Longoria said during an interview on E!'s red carpet.
Topping off her Golden Globes look with the most style was Tracee Ellis Ross who wore a Stephen Jones for Marc Jacobs turban that was shown on the designer's Spring 2018 runway.
And when "Big Little Lies" won for Best Limited Series, Reese Witherspoon thanked the audience and those watching at home: "This show is so much about the life we present to the world that can be very different than the life behind closed doors, so I want to thank everyone who broke their silence this year and spoke up about abuse and harassment". We see you. We hear you. "Instead of distracting from the real issue with a mandate to wear one particular color".
This isn't the first time women have taken control of the carpet.
