Wittels died yesterday at his home. He was 30. The executive producer died of an apparent drug overdose, reported Variety.
Poehler, 43, while remembering Wittels at an event, which happened just hours after he was found dead, said, "Today, I lost a friend. I lost a dear, young friend in my life who was struggling with addiction.
"I'm sharing it with you because life and death live so close together, and we walk that fine line everyday. When things happen in our lives, we turn to the people that we love... And we lean on people, in a hope that we will ease our pain," she said.
