Charlie Puth is the latest celebrity to support March for Our Lives. His contribution to the movement? An "inspirational" new song that he plans to perform at the gathering in Los Angeles on Saturday (March 24).

Speaking to Zane Lowe on Beats 1, the artist explained that even though "nobody knows the song," which also features James Taylor, he will perform it on his piano at the event.

Puth also shared his hope that when people hear the song, they'll be inspired to jump into action and make a difference.

"It's important for me that I'm there this weekend, and no one has prepped me on this question or anything, this is literally just like me thinking of this right now. When they reached out to me and said that they would love to hear a record like 'See You Again' at the march...I wrote 'See You Again' for people and I wrote 'See You Again' to honor my friend, and then it transcended into honoring Paul Walker," he explained.

"It's about everybody, as humans we all help each other and that song came about through collaboration," the singer continued. "So if people at that march on Saturday see me perform that song...hopefully something inspirational will come out of them where they leave that march that day when they leave all that big vibe of inspiration and they’re back in the city life where people are pretty self consumed with what they're doing, they're going to take that with them. This is the most important song I ever wrote."

Puth joins a long list of stars who have voiced their support of the March for Our Lives movement, including Harry Styles, Justin Bieber, Paramore's Hayley Williams, St. Vincent, George and Amal Clooney, Scooter Braun, Lady Gaga, Fifth Harmony's Lauren Jauregui, Amy Schumer, Jimmy Fallon, Oprah and more.
