Frankie Grande took to Instagram on Wednesday to pay tribute to Mac Miller.
"I am beyond heartbroken over Malcolm’s death. He was a good friend and was wonderful to my sister," he wrote.
"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."
Grande continued, "Malcom my friend, you will be dearly missed. and I know you will be looking down on me from heaven, proud AF for every day I live my life clean and sober… 453 days and counting. Thank you from the bottom of my heart."
