Tributes have flooded in for the late Dame Elizabeth Taylor in the wake of her death, with Sir Elton John describing her as a "Hollywood giant."

The screen legend passed away at 1.28 a.m. on Wednesday morning at Los Angeles' Cedars-Sinai Medical Center -- where she had been receiving treatment for the last few weeks for congestive heart failure -- surrounded by her four children, Michael Wilding, Christopher Wilding, Liza Todd and Maria Burton.

Since the news, numerous stars who knew her, or admired her during her life have paid their respects.

Elton, 63, wrote on his Twitter page: "We have just lost a Hollywood giant; more importantly, we have lost an incredible human being."

Whoopi Goldberg mourned the loss of her "diamond loving" friend on her Facebook page, thanking the 'Cleopatra' star for helping her during her career.

She wrote: "Today my friend Elizabeth Taylor passed away. Oddly, we all knew this day was coming but still her passing took my breath away. She was a funny, loud, joke tellin', diamond loving, fantastic woman. She played a big role in shaping my life as Whoopi Goldberg. It really is the end of an era."

Sir Michael Caine -- who starred in the 1972 movie 'Zee and Co' with Taylor -- paid tribute to the person rather than the actress.

He tweeted: "So sad to hear about my beautiful friend Elizabeth Taylor she was a great human being."

The double-Oscar winning actress' representative has revealed her final moments were peaceful, and although her condition worsened at 6 p.m. on Tuesday night doctors had been positive about her illness.

The rep' said: "She died peacefully. Though she had recently suffered a number of complications, her condition had stabilized and it was hoped that she would be able to return home. Sadly, this was not to be."

As well as her four children, Taylor -- who was married eight times to seven different men -- is survived by 10 grandchildren and four great-grandchildren.
