The 'Hamilton' and 'Dear Evan Hansen' stars will perform their musical mash-up single "Found/Tonight" during the Washington, D.C., event Saturday.

More Hollywood stars are ready to do their part in supporting the March for Our Lives rally, as Ben Platt and Lin-Manuel Miranda were announced Thursday to be joining the performance lineup on the D.C. stage for Saturday's demonstration. 

Making the announcement via their Twitter accounts Thursday, the performers expressed their excitement to be a part of the event and praised the students for their activism. "It's been a privilege to follow their example and it’ll be a privilege to stand beside them," Platt wrote on Twitter.

Meanwhile, Miranda asked his followers to rally with them, as he and Platt will also march alongside the students.

The pair will perform "Found/Tonight," a mashup of their previously recorded songs from both Hamilton and Dear Evan Hansen musicals ("You Will Be Found" and "The Story of Tonight"). As announced on the March for Our Lives Twitter, all proceeds from charity single will be donated to the organization.

Miranda and Platt join previously announced performers Common, Miley Cyrus, Andra Day, Ariana Grande, Jennifer Hudson, Demi Lovato and Vic Mensa, along with other surprise guests.

Platt and Miranda also join other stars expected to attend some of the rallies around the country this weekend such as Jimmy Fallon, Samantha Bee, Amy Schumer, Yara Shahidi, Connie Britton, Olivia Wilde and Skai Jackson. Steven Spielberg and Kate Capshaw, Jeffrey and Marilyn Katzenberg, George and Amal Clooney, and Oprah Winfrey have also each donated $500,000 to support the cause.

This week, a letter penned by former President Barack Obama and former first lady Michelle Obama to the Parkland shooting survivors was shared on Twitter via Mic, where they expressed how they feel "inspired" by the students' activism and commend their "awakening the conscience of our nation."

The main march will be held in Washington, D.C., on Saturday at 10 a.m. ET, while sister events will take place in cities including Los Angeles, Boston, New York and Chicago, according to the March for Our Lives website. The L.A. event starts at 9 a.m. PT.
