Rapper Mac Miller was found dead Friday at his San Fernando Valley home following an apparent drug overdose, according to TMZ.

A male caller reportedly contacted 911 from Miller’s home at around noon. Law enforcement sources told the tabloid that the “Cinderella” rapper was found unresponsive in his bedroom. An emergency dispatch indicated that they were called to the home for a patient in cardiac arrest.

Miller, whose real name is Malcolm James McCormick, reportedly battled substance abuse for years.

According to Variety, the Los Angeles Attorney’s Office charged Miller last month for a DUI related to a car accident in the San Fernando Valley. TMZ reported that Miller crashed his G-Wagon into a utility pole and fled the scene. Police caught up with the rapper at his home, where he allegedly blew twice the legal limit.

In late May, singer Ariana Grande revealed that Miller’s addiction played a large role in their recent breakup.

“I am not a babysitter or a mother and no woman should feel that they need to be,” Grande wrote on Twitter. “I have cared for him and tried to support his sobriety and prayed for his balance for years (and always will of course) but shaming/blaming women for a man’s inability to keep his s**t together is a very major problem.”
