According to TMZ, Miller was found by police at his home in California's San Fernando Valley, and pronounced dead at the scene. "At this time, an autopsy is pending and a cause of death has not been determined".
On Friday, fans, friends, and celebrities rushed to Twitter to express their condolences and sadness over Miller's passing.
A coroner's van was seen arriving at the scene shortly before 2.30pm. About 10 news vans remained.
Pittsburgh Slim, a rapper from Miller's home town, also visited and placed a bouquet of flowers at the door of the house. But beyond helping me launch my career he was one of the sweetest guys I ever knew. "I'm completely broken. God bless him".

"I made a stupid mistake".
In late July, Miller sat down with Zane Lowe to for an interview on Beats 1 with Apple Music. "I needed that. I needed to run into that light pole and literally like have the whole thing stop". His more goofy songs included Nikes on My Feet, Kool Aid & Frozen Pizza and Knock Knock.
In 2011, Miller wrote a song about becoming fabulously wealthy and, seeking a metaphor, entitled the song Donald Trump. He then asked Grande if she'd be interested in a duet together.
In 2013, his sophomore effort, "Watching Movies with the Sound Off", entered the Billboard 200 at No.3.
