Though her condition is not thought to be life threatening. But Prince Frederic told website TMZ: “I just called an ambulance. She has to go back to UCLA.”
Her spokesman Ed Lozzi confirmed later: “She is not in a life-threatening situation.”
Zsa Zsa has suffered ill health all year and spent most of August in hospital after hip replacement surgery.
The Hollywood legend suffered further complications after the operation including a blood clot, for which she had to have more surgery, and at one point her condition worsened to the point where she was read the last rites by a priest.
However, the Hungarian-born actress left hospital the very next day on her own insistence, with her husband saying she wanted to live out her final days at home.
Her spokesperson said at the time: “Her health has been up and down ever since her hip replacement. She wanted to spend her final days at home. It is a very difficult time for her family.”
Zsa Zsa’s career spans five decades and includes cinema classics ‘A Touch Of Evil’ and ‘For The First Time’.
She has also famously been married nine times, and has one daughter, Francesca Hilton, by her second husband, hotel magnate Conrad Hilton.
