LOS ANGELES — Actress Zsa Zsa Gabor was hospitalized in critical condition Friday and might have suffered a stroke while undergoing hip replacement surgery after a fall at her Bel-Air home, her publicist said.John Blanchette said he spoke to Gabor's husband on Thursday and was told the 93-year-old actress "was bleeding excessively" and was not responding to surgery."She hasn't talked. She wasn't speaking. They were worried about that. They took her off morphine to see if that might be the cause," Blanchette said. "She's vacant."
