Zsa Zsa Gabor’s ailing health took a turn for the worse Sunday night when she was taken to the hospital to have the lower part of her right leg amputated, People reports. “She developed a lesion on the leg that had swollen a while back and caused her to go to the hospital for treatment, but it has not responded,” said Gabor’s spokesman, John Blanchette. “In fact, it has increased in size, and the doctors have wanted to operate for several days…. [Gabor’s husband, Prince Frederic von Anhal] and Zsa Zsa asked if they could spend New Year’s at home, and [they] shared champagne and caviar. The doctors came to the house today [Sunday], and when they unwrapped the bandages, [they saw that] the wound had festered and they were afraid of gangrene developing, which would be life-threatening.”

Gabor will lose the lower half of her leg below the knee.

Last summer, Gabor had surgery to replace her hip, which she’d broken in a fall; three weeks later she was rushed to the hospital to have a blood clot removed. The actress has been in a wheelchair since being paralyzed in a 2002 automobile accident, and she had a stroke in 2005.

UPDATE: Doctors have decided to delay amputation while they attempt to treat Gabor’s leg with antibiotics.
