The 2018 March for Our Lives is underway in Washington, D.C., Los Angeles and many more cities across the nation, and during Saturday's event (March 24) in D.C., Demi Lovato graced the stage to perform the song "Skyscraper."

"You can break everything I am/Like I'm made of glass/Like I'm made of paper/Go on and try to tear me down/I will be rising from the ground/Like a skyscraper," Demi belted out as the large crowds sang along with her. "MSD strong!" the singer yelled at the end of her performance, showing support to the Majory Stoneman Douglas High School victims.

In related news, Lovato recently celebrated six years of sobriety during a concert in Brooklyn. Just officially turned 6 years sober. So grateful for another year of joy, health and happiness,” the singer tweeted. “It IS possible.

During a stop on her tour in New York, Lovato broke down while talking to her fans about her accomplishment and calling the day a really big day for her. "Yesterday, six years ago, I was drinking vodka out of a Sprite bottle at nine in the morning, throwing up in the car and I just remember thinking, 'This is no longer cute. This is no longer fun. And I'm just like my dad,'" she said.
