The "School of Rock" star is known for his comedy talents, but he admits his early career years were marred by drugs, divorce and the death of his sibling Howard, aged 31, reported Us magazine.
"Losing a family member is the worst thing I could imagine. Death didn't happen quickly. We all saw the deterioration. He was so very young. We were robbed of something precious. It was devastating. It was hard for all of us, but it was hardest for my mom when we lost Howard. She's never really recovered," Black said.
