The “No Tears Left to Cry” singer, 25, has not spoken out about her ex’s death, but her last Instagram post was made on Thursday when she took a short video of her hotel room in the United Kingdom.
“Bye London,” she wrote in the caption.
Miller, 26, was pronounced dead at 11:51 a.m. at his Studio City, California, home, the Los Angeles County Department of Medical Examiner-Coroner confirmed in a statement to PEOPLE.
A cause of death is yet to be determined, but a source tells PEOPLE the rapper had gone into cardiac arrest after appearing to suffer a drug overdose.
Grande and Miller, who struggled with drugs throughout his life, dated for two yearsbefore separating in May.
The split came as a shock to fans as Miller raved about the singer on Twitter in April after she released her single “No Tears Left to Cry.”
“I respect and adore him endlessly and am grateful to have him in my life in any form, at all times regardless of how our relationship changes or what the universe holds for each of us!” the singer wrote.
Grande’s fans came to her defense on Twitter writing it wasn’t the singer’s fault Miller had died.
Another shared the same sentiment, tweeting, “The amount of tweets blamingAriana Grandefor what happened to Mac Miller is disgusting, his addiction and lack of help is what drove this to happen, don’t point the finger and blame.”
A different fan wrote, “Ariana Grandeis not responsible for Mac Miller’s death. Stop hating her. She’s a person like you who also has feelings. I’m sure she’s having a hard time. I wish patience to her and his family.”
Months before his death, Miller wasarrested for drunk drivingon May 14.
Early that morning, the rapper was arrested for DUI and hit and run after he struck a power pole in the San Fernando Valley with his Mercedes-Benz G-Wagon and fled the scene; after law enforcement officers matched the vehicle’s license plates to Miller’s address, they arrested him at his home, a Los Angeles Police Department public information officer previously told PEOPLE.
The rapper went on to open up about his arrest during a conversation with Zane Lowe on Beats 1 on Apple Music in July.
“I made a stupid mistake. I’m a human being,” Miller explained. “But it was the best thing that could have happened. Best thing that could have happened. I needed that. I needed to run into that light pole and literally have the whole thing stop.”
However, Miller went on to let all of his fans know that they shouldn’t worry about him, because he was doing fine.

“I have people that care about me and fans that love my music and it’s a beautiful relationship with them — people who have been with me through being a 19-year-old wide-eyed kid to being a self-destructive depressed drug user to making love music to all these different stages. Then they see something like that and they worry,” he explained. “So your first reaction is, ‘Let me tell them I’m cool.’ ”
During the interview, Miller also explained that both he and Grande had moved on since their split — and that he wished her well.
“I was in love with somebody. We were together for two years. We worked through good times, bad times, stress and everything else. And then it came to an end and we both moved on. And it’s that simple,” he said.
“It’s all positive energy,” he added. “I am happy for her and [the fact that she’s] moving forward with her life, just as I’m sure she is with me.”
