UPDATE 1: TMZ is reporting she sustained a MASSIVE heart attack.

UPDATE 2: Carrie's brother, Todd Fisher, has told the Associated Press that she was "out of emergency" and stabilized at a Los Angeles hospital.

UPDATE 3: Contrary to earlier reports, Todd Fisher has now told AP and several other press outlets that Fisher’s condition is currently uncertain, and that the actress is in Intensive Care. “She’s in the ICU and everybody’s praying for her,” Todd Fisher told Variety during a phone interview. “There’s nothing new from the doctors. There’s nothing new at all. … There’s no good news or bad news.”

UPDATE 4: On Christmas Day, Carrie Fisher's mother Debbie Reynolds spoke out after her daughter suffered a heart attack. "Carrie is in stable condition. If there is a change, we will share it."
