Support: Ariana Grande performed at the March For Our Lives rally in Washington D.C. on Saturday

‘This is for these brilliant students here today that are leading this march,’ she added.

She also sported a We Call B.S. pin as she posed with a group of fans afterwards.

Ariana was part of a group of entertainers – including Miley Cyrus, Jennifer Hudson, and Lin-Manuel Miranda – that performed in support of the march that was organized after the Parkland, Florida high school shooting that left 17 dead on February 14.

Her performance comes nearly a year after 22 people died from a terrorist attack at her concert in Manchester, England.

On June 4, she gave a tribute concert – her first performance after the attack – in honor of the victims called One Love Manchester.

‘I want to thank you from the bottom of my heart for being here today,’ the singer said on stage.

‘I want to thank you so much for coming together and being so loving and strong and unified.

‘I love you guys so much and I think that the kind of love and unity you’re displaying is the kind of medicine that the world really needs right now.’

Ariana also performed at the Charlottesville concert in September that raised money for the victims of the nationalist rally where a driver ran his car into the crowd.

For the people: ‘This is for these brilliant students here today that are leading this march’
