Eilish performed Labrinth’s “Never Felt So Alone,” a song that appeared in the HBO series’ second season and featured her vocals.
“RIP to Angus Cloud,” she said before a sea of fans in Grant Park.
Cloud, who played Fezco on “Euphoria,” died at his family’s Oakland, California, home on Monday. He was 25.
In a statement, the family said that Cloud “intensely struggled” with feelings of loss after his father’s recent burial.
Another, Zendaya, said that words alone couldn’t capture the actor’s “infinite beauty.”
“I’m so grateful I got the chance to know him in this life, to call him a brother, to see his warm kind eyes and bright smile, or hear his infectious cackle of a laugh (I’m smiling now just thinking of it),” she wrote on Instagram.
“I know people use this expression often when talking about folks they love...‘they could light up any room they entered’ but boy let me tell you, he was the best at it.”
Cloud’s co-star Dominic Fike remarked on the actor’s “spark” during a concert Tuesday in Houston.
“I haven’t had a lot of death happen around me, and this was the first time I feel like I knew the person well enough to cry over and feel something,” Fike said.
“I sometimes look at people like sparks. I zoom out and I think people have wavelengths. And if you zoom out far enough, maybe some people you see — probably not a lot of us at all — but I think if you zoomed out millions of miles, you would see this kid’s spark. You could see it from so far away, even if it was a short flash. He would light up a room, any room he walked in.”
