Born Malcolm McCormick in Jan. 19,1992, Miller was raised in Point Breeze and graduated from Allderdice High School in 2010.
"We are deeply saddened to have learned about the tragic passing of 2010 Pittsburgh Allderdice alum Mac Miller. We wish to extend our deepest condolences to his family and friends," a release from Pittsburgh Public Schools said.
From 2016 to 2018 Miller dated pop star Ariana Grande, though the two publicly separated and she is now engaged to comedian Pete Davidson.
Earlier this year Miller was arrested after allegedly crashing into a telephone pole while driving under the influence and fleeing the scene with two passengers.
Miller was set to embark on a North American tour in October.
