"Je suis Charlie" signs and badges appear to be the latest celebrity accessory.

Instead of showing support for research into breast cancer or AIDS, as represented by the pink and red ribbons that used to be the in symbols of solidarity, several celebrities at Sunday night's Golden Globes walked the red carpet honoring French satirical magazine Charlie Hebdo, 12 of whose staff members were killed in a terror attack in Paris on Wednesday.

"Today was an extraordinary day," actor and director George Clooney, sporting a "Je suis Charlie" button on his tuxedo, said in his acceptance speech for the Cecil B. DeMille lifetime achievement award. "Millions of people – not just in Paris but around the world, Christians and Jews and Muslims, leaders of countries all over the world – they didn't march in protest, they marched in support of the idea that we will not walk in fear. We won't do it. So je suis Charlie." (WATCH below)

About 3.7 million people marched in France to honor the victims of the Charlie Hebdo attack and the attack on a kosher supermarket in Paris on Friday, which left four dead, a French official said, making it the largest demonstration in French history.

In addition to Clooney and the human rights lawyer he married this year, Amal Clooney (whose "Je suis Charlie" badge adorned her purse), other celebrities sporting the latest in Paris solidarity fashion include Helen Mirren, Joshua Jackson and Diane Kruger, who held up signs with the phrase, and Kathy Bates held up the message on her phone, ABC News said.

"Laughter and satire will never disappear, and will always be the most effective tools for a free world," producer and studio executive Harvey Weinstein wrote in Variety on Sunday. "One of the greatest movies of all time had one of the most romantic lines ever spoken in a film: Humphrey Bogart to Ingrid Bergman, “We’ll always have Paris.” Whenever I think of Paris, I will always think of the romance, but more importantly I will think of Charlie Hebdo and the romance of its greatness."

The phrase "Je suis Charlie" also appeared at the end of this week's Simpsons episode, in the form of a sign held up by Maggie, in what appears to be an imitation of the Eugene Delacroix painting "Liberty Leading the People."
