Chelsea Handler will lead a "Women's March" down Main Street in Park City,Sex On Phone Utah, during the Sundance Film Festival later this month to coincide with the Women's March in Washington, D.C., Mashablecan exclusively report.

If everything comes together as planned, Handler will lead the procession -- which is not affiliated with the festival -- on Saturday, Jan. 21, from 9 a.m. to 11 a.m. local time. It's one of more than 200 sister marches planned in all 50 states and in 20 countries around the world.

With the creation of a Facebook page sometime last month, organizers revealed the Women's March on Main, and rumors had been swirling about Handler's involvement for days.

"Sundance has always been a platform for change: not only for filmmakers and filmmaking, but also for big ideas for the future," Handler told Mashablein a statement. "If there's anything I learned in the last year, it's that we need to be louder and stronger than ever about what we believe in, so I joined some incredible women from around the country to bring our voices together in the streets of Park City. The Women’s March on Main will be an opportunity for the creative community and those in Utah to stand beside those in D.C."

Handler was at the festival last year to promote Chelsea Doesfor Netflix, which has become a major player at Sundance. It wasn't immediately clear whether the streaming service would be involved with the Women's March.

TheWrap, which was first to report on the rally Wednesday, said several celebrities were expected in attendance, including Jennifer Aniston, Geena Davis, Salma Hayek, Melissa Leo, Elizabeth Olsen and Rooney Mara.

Though it's certainly no coincidence that the marches are being held the day after the inauguration of President-elect Donald Trump, organizers took care to point out that it is not an "anti-Trump" demonstration -- but is rather to promote "universal respect for social justice and human rights issues ranging from race, ethnicity, gender, religion, immigration and health care."

Park City's half-mile-long Main Street is already a bustling thoroughfare during Sundance, which routinely attracts a healthy crop of actors, directors, executives and other filmmaking luminaries for the largest independent film festival in the U.S.

And if we've learned anything from festivals past, weather could be a factor.
