Bret Michaels remained in critical condition after suffering a massive brain hemorrhage.
The Poison frontman and Celebrity Apprentice star, 47, was rushed to an undisclosed hospital late Thursday after complaining of a painful headache. Doctors found Michaels was bleeding at the base of his brain.
"He is under 24 hour doctors' care and supervision. We are hopeful that further tests will locate the source of the bleeding, which has still not been located," a statement on his website said Sunday. "As we all know Bret is a fighter and we are hopeful that once all is complete the slurred speech, blurred vision and dizziness ... will be eliminated and all functions will return to normal."
