Celebs including Miley Cyrus, The Rock post support for ‘March for Our Lives’

Celebrities are expressing support for the “March for Our Lives” rallies for gun reform taking place on Saturday.

Dwayne “The Rock” Johnson took to Twitter on Saturday morning to urge adults and politicians to “listen and do” something to protect children. Johnson, who has acknowledged he might run for office someday, noted that he stands for "open dialogue and action."

Kim Kardashian also tweeted that she is in Washington, D.C., with her husband Kanye West and daughter North to participate in the “March for Our Lives” rally there.

Organizers of the D.C. march obtained a permit for 500,000 people to rally around Pennsylvania Avenue near the White House, but many expect turnout to exceed such figures.

"One of my best friends was killed in gun violence right around here, so it's important to me," Paul McCartney told CNN as he marched in New York City, referring to John Lennon who was shot in 1980.

As the march neared, more stars began to express support for the rally. Even Taylor Swift, who tends to shy away from political statements, said she had donated to the students organizing the march.

A number of celebrities, including Oprah Winfrey, John Legend, Chrissy Teigen and George and Amal Clooney donated money to organize the rally.

George Clooney wrote a letter to the editors of the Marjory Stoneman Douglas High School newspaper, The Eagle Eye, telling them they make him proud of his country again and expressing his support for the march.

Miley Cyrus and Demi Lovato, who are scheduled to perform at the D.C. rally, took to Twitter to support the rally and remind people to tune in.

Pop stars Ariana Grande, Common, Jennifer Hudson, Vic Mensa and Andra Day are also all scheduled to perform in D.C.
