The star, known for her role in the 1968 hit film "Rosemary's Baby," tells "Entertainment Tonight" her doctor has ordered her to come off the liquid diet because she is putting her health in danger.

Farrow began fasting almost two weeks ago to bring awareness to the humanitarian crisis in Darfur.

The 64-year-old said she was told to stop the fasting immediately because she could have started suffering seizures had she continued.

She added, quote, "I am fortunate.

The women, children and men I am fasting for do not have this option."

British billionaire Richard Branson is taking over from Farrow and will go on a hunger strike for the same cause.

He tells "ET" he is honored to be taking over from the former model after he traveled to Darfur a year and a half ago.

Branson said he was, quote, "horrified by the stories that people of all ages shared with us." He adds that he simply can't stand by and watch one million people suffer.
