According to Mac Miller's friend, even after their breakup, Ariana Grande was the MOST supportive of his sobriety.
Sources on Ari's said have said she's inconsolable and can't believe that Mac is really gone. Shadiness around the breakup or not, you can't help but feel for the girl -- the dude she loved and was with for a couple years passed away...no matter what happens as far as breakups and stuff, that'll definitely leave a mark.
Mac Miller's friend Shane Powers on Ariana Grande: "...there was no one in his life more ready to go to the wall for him when it came to him being sober. She was an unbelievably stabilizing force in his life.” https://t.co/sBfC2N5K9f— Perez Hilton (@PerezHilton) September 11, 2018
