"I'm a very sensitive person... but this Mac Miller shit got me fucked up," Glover said on stage, as per Rolling Stone.

"He was the sweetest guy, he was so nice. And we were both, you know, kind of internet music kids, because, you know, we came up on the internet, and a lot of critics were like, 'This corny-ass white dude,' just like they were like, 'This corny-ass black dude,' and we used to talk. And this kid, he just loved music.

"And we should be allowed to be sad about that. Like my heart was broken... and I feel good about being sad, because it tells me that he was special, that I had a special moment... Everybody deserves that, everybody in this room."

According to the publisher, Glover dedicated his song "Riot" to Miller.

"I just want to tell you that I love you and this song is for him, because I feel like sometimes he wanted to let go," he said.

Miller, whose real name is Malcolm McCormick, passed away on Friday, with reports attributing his death to a drug overdose, including TMZ . Miller's family confirmed his death in a statement published by Rolling Stone, but did not reveal any details about his cause of death.

"He was a bright light in this world for his family, friends and fans. Thank you for your prayers. Please respect our privacy. There are no further details as to the cause of his death at this time," the statement read.

Fellow artists like Chance the Rapper, Ed Sheeran, and Solange Knowles also paid their respects to Miller, posting tributes on social media.

There has been significant media attention placed on Miller's ex-partner Ariana Grande, following the rapper's death.

The pair dated from 2016 until mid-2018. Grande posted a single photo on Instagram on Saturday, with no caption. Now leave her alone.
