Carrie Fisher's Mother Debbie Reynolds Thanks Fans for Their Support

Fisher was hospitalized Friday after going into cardiac arrest on a flight.

Reynolds tweeted today:

While Reynolds used the term "stable," it is not an official medical status and Fisher's condition was not clear.

Fisher's brother, Todd, told ABC News on Friday that the actress was receiving care from "the very best" doctors.

“We just need to tell everybody to keep the prayers up because the doctors are doing everything they can for her right now,” he said. “She’s a real survivor and always has been and I would expect the best from this. That’s how we’re approaching it.”
