'We are fighting for change!' Ariana Grande puts on moving performance in thigh-high boots and statement top at March For Our Lives rally.

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

The pop star wore a sweatshirt with the name of the event as she sang Be Alright in front of a crowd of students gathered together in protest of gun violence.

‘We’re fighting for change and love and safety and for our future. I love you all so much,’ the 24-year-old told the crowd after her rousing rendition.

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.
