Oscar-nominated actor Michael Clarke Duncan has died, his fiancé Omarosa Manigault confirms. The Green Mile star, 54, passed away on Monday morning after spending nearly two months in the hospital following a July 13 heart attack. 
Best known for his breakthrough performance as gentle giant death row inmate John Coffey in The Green Mile, Duncan also starred in dozens of blockbusters, including Armageddon, Planet of the Apes and Kung Fu Panda. Before becoming an Oscar nominee, Duncan worked as security guard in Hollywood for celebrities such as Will Smith, Martin Lawrence, Jamie Foxx, LL Cool J, and Notorious B.I.G.
The 6'5" actor suffered cardiac arrest in the wee hours of the morning on July 13, but was discovered by Omarosa who performed CPR on the actor and possibly saved his life. He was then rushed to the hospital and was said to be making a slow-but-steady recovery, until his death on Monday. 
Our thoughts and prayers are with Duncan's family.
