Ariana and Mac made their relationship Instagram official in September 2016 , but they have been friends since around 2012. They first sparked dating rumors in August 2016 after they were spotted hanging out together at Disneyland and walking through an airport together.
Last year, Ariana revealed in an interview with Cosmopolitan that she had feeling for the "Smile Back" spitter for a long time. "We have loved and adored and respected each other since the beginning, since before we even met, just because we were fans of each other's talent," she said.
Explaining why the didn't begin dating sooner, Ariana told the mag, "We weren't ready at all, though, to be together. It's just timing. We both needed to experience some things, but the love has been there the whole time."
Prior to dating Mac, Ariana was linked to her backup dancer Ricky Alvalrez. The petite diva also once dated her "Right There" and "Best Mistake" collaborator Big Sean in addition to dating her "Almost Is Never Enough" duet partner Nathan Sykes.
