Miller was found unresponsive at his home in San Fernando Valley. While no official cause of death has yet been released, Miller is believed to have died from an apparent overdose.
There has been a lot of speculation as to how Grande would publicly respond to Miller’s death following their 2-year relationship, which ended in May this year.
Grande shared the personal snap without a caption.
The “God Is a Woman” singer disabled comments on Instagram following an influx of angry comments in response to the news of Miller’s death.
Grande faced similar online harassment after Miller was charged with a DUI earlier this year and released a statement about his trouble with addiction.
“Of course I didn’t share how hard or scary it was while it was happening, but it was. I will continue to pray from the bottom of my heart that he figures it all out and that any woman in this position does as well.”
Miller had spoken openly about his substance abuse issues.
Speaking to Billboard in 2015, he detailed his difficulties following the success of his debut record: “I was doing a lot of drugs around that time, which is another difference now: I’m not doing as many drugs…It just eats at your mind, doing drugs every single day, every second. It’s rough on your body.”
Miller was due to start a tour next month in support of his latest, critically acclaimed album, ‘Swimming’. NME called it “his best work in years”.
The day before his death (September 6), Miller performed an intimate performance at the Hotel Cafe in Hollywood. An official video of the performance was posted online:
Tributes to Miller are widespread on social media, with artists including Chance the Rapper, Earl, the 1975 and Missy Elliot paying tribute.
