But now the No Tears Left To Cry singer has taken to her Instagram story to share with fans her side of the story in a more intimate fashion.
"Hi! This is one of my best friends in the whole world and favourite people on the planet Malcolm McCormick," Grande wrote. "I respect and adore him endlessly and am grateful to have him in my life in any form, at all times regardless of how our relationship changes or what the universe holds for each of us!"
"Unconditional love is not selfish. It is wanting the best for that person even if at the moment, it's not you," she continued. "I can't wait to know and support you forever and I'm so proud of you!!" she shared with a picture of the former couple.
Ariana, 24, and Mac Miller, 26, went public with their relationship in August 2016.
