“The Green Mile” star and Academy Award-nominated Michael Clarke Duncan is in the intensive care unit (ICU), after going in to cardiac arrest Friday morning, and his girlfriend, reality show villainess Omarosa Stallworth, actually saved his life.

Stallworth reportedly discovered that Duncan was unconscious and barely breathing at around 2:00 a.m. Acting quickly, Stallworth reportedly began to perform emergency CPR, which resuscitated him.

The 54-year-old Duncan, who is 6’5 and more than 315 pounds, was transported to the ICU of a nearby hospital, and according to sources, his heart is stable. In addition, Omarosa, his girlfriend of two years, has not left his side throughout the entire episode.

Doctors are now working to find out why Duncan’s heart failed in the first place.

In 2009, Duncan stopped eating meat, became a staunch vegetarian, and began touting the benefits of living a healthy lifestyle.
