Actress Elizabeth Taylor has been admitted to a Los Angeles hospital to treat symptoms of congestive heart failure.
The 78-year-old was taken to Cedars-Sinai Medical Center for the "ongoing health problem", spokesperson Sally Morrison said.
"Her family and close friends are appreciative of the warm support and interest of her loyal fans but have asked that people respect her privacy and allow her medical team the time and space to focus on restoring her back to health," the BBC quoted a statement issued on Friday as saying.
Dame Elizabeth has a long history of medical problems and underwent heart surgery in 2009.
She was supposed to attend an award at a benefit gala for HIV/Aids charity amfAR on Wednesday in New York, but missed the event.
