A representative for the late star confirmed her death to the PA news agency on Sunday.
On Friday, the 53-year-old was legally declared dead after suffering a "severe anoxic brain injury" while crashing her car into a house in LA.
She had been kept on life support in case her organs could be donated.
It is not known how many or which organs will be donated but, according to NBC News, surgeons were ready to perform the implants.
