Frankie Grande 'Beyond Heartbroken' Over Mac Miller's Death

"He was a good friend and was wonderful to my sister. "

Following the death of Mac Miller (real name Malcolm McCormick), Frankie Grande -- brother of Miller's ex Ariana Grande -- has penned a sweet tribute to the rapper over social media.

Revealing that the late rapper was instrumental in encouraging him to seek treatment for his own drug and alcohol issues, he wrote in a lengthy Instagram caption:

"I am beyond heartbroken over Malcolm’s death. He was a good friend and was wonderful to my sister. He was the reason I went to the rehabilitation centre where I was detoxed safely from all of the drugs alcohol and medications I was taking, when I couldn’t imagine living without them," Frankie wrote. "It was the place where I found the community of support that showed me that living life without drugs was a possibility and I would never have discovered that if it weren’t for Malcolm."

He added that the 26-year-old would also celebrate sober milestones, saying that Mac "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."

Frankie's tribute comes after sister Ariana was forced to turn off comments on her Instagram following a torrent of abuse from fans of the artist, who (unfairly) blamed his death on the 25-year-old singer, saying it was a result of her ending their two-year relationship.

In just May this year, Ariana famously clapped back at fans who said the rapper's DUI was her fault, writing on Twitter:

"I have cared for him and tried to support his sobriety & prayed for his balance for years," she continued. "(And always will of course) but shaming / blaming women for a man's inability to keep his shit together is a very major problem. Let's please stop doing that."

Miller's close friend Shane Powers came out in defence of the "God Is A Woman" songstress yesterday, telling listeners on his podcast show that Ari "was an unbelievably stabilising force in his life and she was deeply helpful and effective in keeping Mac sober."

Miller was found dead on Friday September 7 from an apparent overdose.
