Oscar-nominated actress Debbie Reynolds released a statement on Christmas about the health of her daughter, Carrie Fisher, who had a heart attack on a flight from London to Los Angeles Friday. The “Star Wars” actress was placed on a ventilator at UCLA Medical Center.

Reynolds, 84, took to Twitter Sunday to update Fisher’s fans. “Carrie is in stable condition,” she wrote to her 26,000 followers. “If there is a change, we will share it. For all her fans & friends. I thank you for your prayers and good wishes.”

One friend that sent his best was “Star Wars” co-star Harrison Ford. “I’m shocked and saddened to hear the news about my dear friend,” Ford said in a statement to The Hollywood Reporter Saturday. “Our thoughts are with Carrie, her family and friends.”

Fisher shocked fans when she admitted she had affair with Ford while they filmed “Star Wars” in 1976 in her new book, “The Princess Diarist,” which was released last month.

Reynolds made light of the tryst. “Why all the fuss about Carrie's admitting she had an affair with Harrison Ford?” the “Singin’ in the Rain” actress wrote Nov. 16. “I have to admit I slept with her father! New book on 11/22!”

Fisher’s brother, Todd, spoke to multiple news outlets after the 60-year-old was hospitalized.

“She is in the intensive care unit, she is being well looked after,” he told Entertainment Tonight Online Friday. “If everyone could just pray for her that would be good. The doctors are doing their thing and we don't want to bug them. We are waiting by patiently.”

Doctors don’t know what happened to Fisher during the flight. “We hope for the best,” Todd told the publication. “We certainly do not know her condition, that's why she is in ICU. I'm sure everyone wants to speculate, but now is not the time for that.”

While she’s most recognized for “Star Wars,” she also appeared in movies like “When Harry Met Sally,” “Charlie's Angels: Full Throttle,” “The Blues Brothers,” “The Man with One Red Shoe,” “The ‘Burbs,” “Fanboys” and “Hannah and Her Sisters.” She reprised her role as Princess Leia in 2015 for “Star Wars: The Force Awakens.”
