John wasn't the only one to honour the late rapper during his show.
Fellow rapper Childish Gambino - aka Donald Glover - took a moment during his concert in Chicago, admitting: "I'm a very sensitive person…this Mac Miller shit got me f***ed up".
Glover said of Miller: "He was so nice. He was the sweetest guy, he was so nice. And we were both internet music kids and a lot of critics were like; 'This corny-ass white dude, 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 it. 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 in this room deserves that.
"So I just wanna say; I love you Mac. And...this song is for him, because I feel like sometimes he wanted to let go," he said, before dedicating his song Riot to the late rapper.
Rapper G-Eazy also paid tribute to Miller during a show in Florida.
He broke down as he dedicated his song 'Everything Will Be OK' to his friend, projecting a photo of Miller onto the screen behind him.
He told the crowd: "I swear, life is so f***ing fragile. Appreciate the moment. Be present in it. Tell people you love you care about them."
