Comedian and Chicago native Bernie Mac died early Saturday morning from complications due to pneumonia, his publicist confirmed.

Mac, 50, had been hospitalized for about a week at Northwestern Hospital, according to his spokeswoman. A few years ago, Mac disclosed that he suffered from sarcoidosis, a rare autoimmune disease that causes inflammation in tissue, most often in the lungs.

Danica Smith, the comedian's publicist, had said Thursday that Mac's condition was "stable," The Associated Press reported.

"When I got the call this morning, it was just devastating news," said Chicago Sun-Times columnist Stella Foster. "Let's face it: Bernie Mac was one of a kind. He was the best of the best in terms of giving you a good laugh."
