Ariana Grande and rapper Mac Miller have broken up, TMZ reports.
The pair had been dating since September 2016, but Grande took to the Met Gala red carpet solo earlier this week.
Hectic work schedules were reportedly to blame for the break-up, but the couple are apparently still friends.
Grande released her new album 'No Tears Left To Cry' in April, and Miller took to Twitter to show his support.
"Very proud of this girl right here," he wrote. "Welcome back. We missed you. One of a kind."
Miller was said to have been a great source of comfort to Grande in the aftermath of the bombing of her Manchester Arena show in May 2017.
The split comes only weeks after Grande posted an Instagram photo of the pair in a loving embrace at Coachella in April.
