ARIANA Grande and boyfriend Mac Miller have split up due to their manic work schedules.
Boom Boom singer, Ariana, 24 and her rapper beau, 26, have parted ways - but are still good friends, according to .
Their parting has been blamed on their heavy workloads, with her fourth album due out next month.
But the split will shock fans.
Mac recently took to twitter with gushing praise for Ariana as she released new single No Tears Left To Cry.
He tweeted: "Very proud of this girl right here. Welcome back, we missed you. One of a kind."
The pair were also snapped together earlier this year at an Oscars after party in Los Angeles.
