Hollywood icon Elizabeth Taylor is being treated at Cedars-Sinai Medical Center in Los Angeles for symptoms of congestive heart failure, her spokesperson revealed Friday. It is not yet clear how long the Oscar-winner will remain in the hospital. Taylor was originally diagnosed with the condition in November 2004. The now-78-year-old star was scheduled to attend an amfAR benefit gala Wednesday night in New York, where she was to receive an award for her dedication to AIDS research. Elton John accepted the award on the absent Taylor’s behalf. He relayed this message from the actress: "I am there in spirit and I join you in saluting my fellow honorees and all these extraordinary leaders. I am inspired by their example, exhilarated by their vision, and encouraged by their compassion and love. And I love them in return."
