Ariana Grande has been keeping to herself since the tragic passing of her ex-boyfriend Mac Miller, but her brother Frankie has shared an emotional tribute to the late rapper, crediting him with helping him overcome his addiction struggles.

Mac (real name Malcolm James McCormick) was found dead at the age of 26 on September 7, 2018, of an apparent drug overdose, after splitting up with Ariana in May this year following two years of dating.

Ariana, who's since gotten engaged to comedian Pete Davidson, responded to his passing by sharing a sweet photo of her ex to Instagram.

But Frankie, 35, was more vocal about Mac's role in both his and Ariana's lives.

"I am beyond heartbroken over Malcolm's death. He was a good friend and was wonderful to my sister," Frankie captioned a black-and-white picture of Mac on his Instagram.

"He was the reason I went to the rehabilitation center where I was detoxed safely from all of the drugs alcohol and medications I was taking, when I couldn't imagine living without them."

"I remember when I would get 30, 60, 90 days clean and Malcolm would be there with a gift and a card and words of encouragement… telling me that he knew how hard getting sober is and how impressed he was that I was succeeding," he added.

Ariana is reportedly "distraught" over her ex-boyfriend's death and is expected to attend his funeral later this week.

RIP, Mac.
