Joining the likes of Hayley Williams, Justin Bieber, Fifth Harmony's Lauren Jauregui and St. Vincent, Harry Styles has added his name to the list of musicians supporting March For Our Lives. The gathering, which is expected to draw more than 500,000 protesters, is set for March 24 in Washington, D.C. to demand stricter gun control in wake of the Valentine's Day (Feb. 14) mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida.

The singer tweeted that he signed the petition, and was encouraging fans to do the same: "I just signed the @AMarch4OurLives petition, and you should too. H"

The Parkland students have steadily gained traction in their outspoken fight for stricter gun laws, getting nods from Oprah -- who compared them to Civil Rights activists -- and confronting Rep. Sen. Marco Rubio about his stance on gun legislation and fealty to the National Rifle Association during a recent CNN town hall debate

Other celebrities who have voiced their support include Amal and George Clooney, who vowed to donate $500,000 to the march to help accommodate student's travels and needs, a figure reportedly matched by Oprah Winfrey and fashion house Gucci. Jimmy Fallon has also pledged that he will participating in the march, traveling to D.C. to join the high schoolers.
