People all over the world were shocked when rapper Mac Miller passed away earlier this month in Studio City, California — dead of an apparent drug overdose.

The “Donald Trump” musician, who was only 26, had been scheduled to appear in court for a drunk-driving incident.

He had been opening up in recent interviews about his struggle with substance abuse.

Miller’s family is now grieving the rapper and preparing for his funeral.

Miller’s brother, Miller McCormack, was spotted carrying cases of beer on Friday into his parents’ home in Pittsburgh, Pennsylvania.

Miller is an administrator of his brother’s estate, along with the rapper’s lawyer, David Byrnes.

The rapper had written a will when he was only 21 — and the majority of his estate is going to his parents, TMZ reported.

It is unclear how much the musician was worth at the time of his death.

Miller’s parents, Mark and Karen McCormack, released a heartbreaking statement when news of their son’s death broke last week, as the New York Post reported. “Malcolm McCormick, known and adored by fans as Mac Miller, has tragically passed away at the age of 26. He was a bright light in this world for his family, friends and fans. Thank you for your prayers.”

Though he was known primarily as a rapper, Miller taught himself how to play piano, guitar, drums, and bass, according to reports.

Miller was perhaps best known for his song “Donald Trump,” which was released long before the New York-based real estate mogul ever began his run for the presidency.

The song is a celebration of ambition and success.

It includes lyrics such as “Take over the world when I’m on my Donald Trump s***. Look at all this money, ain’t that some s***.”

Miller had recently been in a relationship with fellow singer Ariana Grande.

She took to social media to remember her former boyfriend — she is now engaged to “Saturday Night Live” comedian Pete Davidson.

“I adored you from the day I met you when I was nineteen and I always will,” she wrote on Instagram. “I can’t believe you aren’t here anymore. I really can’t wrap my head around it. We talked about this. So many times. I’m so mad, I’m so sad I don’t know what to do. You were my dearest friend. For so long. Above anything else. I’m so sorry I couldn’t fix or take your pain away … I hope you’re okay now. Rest.”

She paired her note with a video of Miller — in which he’s shown smiling and is seemingly happy.

Fans have also been mourning the singer and sharing their grief and upset through social media.

Mac Miller was set to go on a tour this fall.

His last album was “Swimming,” which was released on August 3 of this year.
