Ariana Grande and boyfriend Mac Miller have reportedly split .

The singer and rapper pulled the plug on their approximately two-year relationship because of busy work schedules, multiple outlets reported Wednesday.

They appeared cozy backstage last month at Coachella, where Grande performed. But thats apparently not the case anymore.

The two had been an item since at least August 2016, when they were seen kissing at a sushi bar . They had collaborated on Grandes 2013 hit The Way and Millers My Favorite Part, Billboard noted.

Miller and Grandes romance spanned a difficult time for the No Tears Left To Cry pop star. She performed at a May 2017 concert in Manchester, England, where 22 were killed in a terrorist bomb attack. The next month, Miller took the stage with Grande at a benefit for the victims and their families.
