Gabor (94) was taken by ambulance to a Los Angeles hospital after having problems with her breathing at home, publicist John Blanchette said.
He said her condition was serious. "They are trying to drain her lungs to save her life," he said.
Gabor has been in and out of the hospital for almost a year after breaking her hip in a fall at her Bel Air home in July.
Her leg was partially amputated in January because of a gangrene infection. She was also treated for pneumonia in February.
The Hungarian-born actress and gossip-page fixture starred in 1950s movies "Moulin Rouge" and "Lili."
