Major cities across America have been host to a number of protests following the death of George Floyd, an unarmed black man who was murdered by former Minneapolis Police Officer Derek Chauvin.

Hundreds of protesters were arrested over the weekend, as disturbing videos of police officers brutalizing civilians began to surface. Nevertheless, thousands and thousands of demonstrators stuck it out in support of the Black Lives Matter movement—and even in protective gear, a few familiar faces were among the crowds.

Here’s a list of celebrities spotted protesting against police brutality.

Ariana Grande

Ariana Grande’s ponytail was seen among a crowd of peaceful protesters in Los Angeles, along with a “Black Lives Matter” sign. “All throughout Beverly Hills and West Hollywood we chanted, people beeped and cheered along,” the pop star tweeted. “We were passionate, we were loud, we were loving.”

Halsey

At some protests, police began using painful rubber bullets, one of which caught Halsey. “This hit me through layers of fabric and for that, I am extremely privileged. At close range it would have caused serious injury,” she wrote in a post on her Instagram story along with a photo of her bruise. “They were fired at peoples’ [sic] faces during peaceful moments of the demonstration. If you’re a follower of mine who ‘stays out of it’ but you’re mad I have a little bruise for doing nothing unlawful, than [sic] consider you ARE on our side. Because the reality of what happens to black folks everyday is worse than my bruise. So get involved. Sign. Donate. Share links. Do something.”
