"I've been struggling with substance abuse since I was 16 years old. Finally at the age of 24 I decided to get some help. With 50 days of sobriety under my belt, I can honestly say I'm the happiest I've ever been," he writes. "I'm thankful for my family and everybody that cares about me, including my fans. I've been blessed with the programs of AA and NA which allow me to rise above this disease. I'm learning to accept my faults and be OK with being human. If anybody that sees this struggles with addiction, feel free to reach out. Thank you all for the love and support!"

Chet, who goes by the stage name Chet Haze, first entered the spotlight as an undergraduate at Northwestern University thanks to his update on Wiz Kalifia's hit "Black and Yellow," this time titled "White and Purple" (the school's colors, natch). He graduated in 2013 with a theater degree, and has since pursued a career in pop music under his company, Kinetik Entertainment.
