Michael Clarke Duncan saved by Omarosa Manigault-Stallworth

Actor Michael Clarke Duncan has his girlfriend, Omarosa Manigault-Stallworth, to thank for saving his life when he went into cardiac arrest Friday.

She discovered him in that state at his Los Angeles home around 2 a.m. and quickly revived him with CPR.

Duncan was then taken to a hospital for treatment and placed in ICU.

"According to doctors, Michael Clarke Duncan suffered a myocardial infarction early this morning," a rep for the actor said. "He is now stable and we look forward to his full recovery."

Tests are also underway in order to determine the cause of the attack.

Manigault-Stallworth is famous for her role on the reality series The Apprentice, where she projected an almost-villainous persona. She also appeared on the reality series Fear Factor and Girls Behaving Badly.

Her spokespeople have not issued a statement.

Duncan, a 54-year-old former bodyguard, is known for his roles in films such as Armageddon (1998), Planet of the Apes (2001) and his Academy Award-nominated role in The Green Mile (1999).
