Taylor, who has a long history of health problems, was taken into Los Angeles' Cedars-Sinai Medical Center on Tuesday (08Feb11), according to her spokesperson.
Representative Sally Morrison reveals the 78-year-old star is being treated for the "ongoing" health problem, but it is unclear how long she will stay in the facility for.
A statement released to Access Hollywood reads, "Elizabeth Taylor was hospitalized earlier this week when she was taken to Cedars-Sinai suffering from symptoms caused by congestive heart failure, an ongoing condition. This issue is being addressed. She is currently being kept in the hospital for monitoring.
"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."
Taylor underwent heart surgery in 2009.
