Though the cause of death has not been confirmed, Mac had been hospitalized recently for pneumonia. Foster said that she received calls early Saturday morning from a close friend of the Mac family, confirming the reports of Mac's death.
"It brought tears to my eyes because Bernie Mac has always been my all-time favorite entertainer and comedian. It pains me to have to report that," Foster said during a phone interview on Saturday morning.
On Friday, a spokeswoman for the actor, whose real name is, Bernard McCullough, said that he had been responding well to treatment for the illness.
Publicist Danica Smith said Thursday in a statement that Mac's condition is ''stable.'' Smith first announced on August 1st that Mac was hospitalized in Chicago.
Smith has said the pneumonia isn't related to an inflammatory lung disease Mac also has. That condition has been in remission since 2005.
Foster noted that last weekend, several web sites reported wrongly that the comedian died.
Mac made waves last month with off-color jokes during a fundraiser for Democratic presidential candidate Barack Obama.
The comedian starred in the critically acclaimed Fox television series ''The Bernie Mac Show.'' His film credits include roles in the ''Ocean's Eleven'' franchise.
The actor's upcoming movies include "Madagascar: Escape 2 Africa" starring Ben Stiller, Chris Rock and David Schwimmer; and "Soul Men" with Samuel L. Jackson and Isaac Hayes.
There is no word on whether public services will be held.
Nothing cute to say whatsoever. He will be missed.
