Elizabeth Taylor is letting friends and fans know that she is about to go to the hospital for heart surgery.

"Any prayers you happen to have lying around I would dearly appreciate. I'll let you know when it's all over. Love you, Elizabeth," the 77-year-old star wrote on her Twitter page Tuesday afternoon.

That message was preceded by two others:

• "Dear Friends, I would like to let you know before it gets in the papers that I am going into the hospital to have a procedure on my heart."

• "It's very new and involves repairing my leaky valve using a clip device, without open heart surgery, so that my heart will function better."

Kelly Osbourne sent well wishes to Taylor over Twitter, writing, "Good luck. My mother I and praying and thinking of you!"

Comedian Sandra Bernhard also tweeted to Taylor saying, "You have weathered harsher storms dear lady, we send every variety of prayer from many lands may they carry you through!"
