Rapper Mac Miller has died from an apparent drug overdose, confirm multiple sources. He was 26 years old.

According to a TMZ report, the Pittsburgh-born artist was found unresponsive by a friend at his Los Angeles home on Friday (September 7). Paramedics were called, and Miller was pronounced dead at the scene.

Miller, whose real name is Malcolm James McCormick, was transparent about his substance-abuse issues during his decade-long career, recently telling Vulture, “I used to rap super openly about really dark shit because that’s what I was experiencing at the time. That’s fine, that’s good, that’s life. It should be all the emotions.”

The MC was arrested for a DUI in association with a car accident in the San Fernando Valley in May. His struggles with addiction were again made evident when his ex-girlfriend, singer Ariana Grande, took to Twitter that same month to address a fan who suggested that the pair’s publicized breakup played a role in the incident.    

“I have cared for him and tried to support his sobriety & prayed for his balance for years (and always will of course),” Grande wrote, “but shaming / blaming women for a man’s inability to keep his shit together is a very major problem.”

Miller began rapping at the age of 14 and made a name for himself through a string of mixtapes, including The High Life, K.I.D.S., and Best Day Ever. His first studio album, Blue Slide Park, was released in 2011 and became the first independently-distributed debut LP to land a number-one spot on the Billboard chart since 1995. Four more compilations, including the critically praised The Divine Feminine and the most recent Swimming, would follow. He also produced tracks under the pseudonym Larry Fisherman.

Fellow artists, celebrities, and industry folks have taken to social media to share their condolences and memories of Miller.
