Michael Clarke Duncan, the Oscar-nominated star of The Green Mile, has died after nearly two months of treatment following a heart attack in July.
Publicist Joy Fehily released a statement from Duncan's partner, the Rev. Omarosa Manigault-Stallworth, saying the 54-year-old actor died on Monday morning in a Los Angeles hospital.
As the sad news was delivered, it also referred to Omarosa for the first time as his fiancée, saying: 'The Oscar-nominated actor suffered a myocardial infarction on July 13 and never fully recovered.'

The 6ft 5in, 300 pound star appeared in dozens of films, including box office hits Armageddon, Planet Of The Apes and Kung Fu Panda.
Duncan had a handful of minor roles before The Green Mile brought him an Academy Award nomination for Best Supporting Actor in 1999, but unfortunately he lost out to Michael Caine after the British legend won his second Oscar to The Cider House Rules.
The film, based on the Stephen King novel of the same name, starred Tom Hanks as a corrections officer at a penitentiary in the 1930s. Duncan played John Coffey, a convicted murderer.
Outpouring of grief: Everyone from Olivia Munn to Evander Holyfield paid tribute to the actor
The role saw him become a global star, with Duncan winning the best supporting actor category for the Black Reel Award, Broadcast Film Critics Association Award and Saturn Award ceremonies.
He was also nominated a further nine times, along with his Oscar nod, receiving recognition at the Golden Globes, MTV Movie Awards and Screen Actors Guild Awards.
As news of the tragic actor was revealed, celebrity tributes poured in via Twitter, with former NBA star Kenny Smith stating he was due to visit Duncan tomorrow.

Before finding fame in Tinseltown, Chicago native Michael worked as a labourer, digging ditches for a gas company.
He then headed to the bright lights of Hollywood, in touching distance of the limelight but still behind the scenes as he found work as a bodyguard for stars including Jamie Foxx and Will Smith.
When one of his clients, the Notorious B.I.G. was killed in 1997, Michael left the security business.

But luck was on his side, and the following year, he landed a role in Armageddon, before going on to star in a string of hits.
He continued his success for over a decade, working right up until his death.
His final role is yet-to-be released From The Rough, a sports drama based on the true story of Catana Starks, a former swimming coach (played by Taraji P. Henson) who became the first woman ever to coach a college men’s golf team.
Duncan was not averse to the occasional flop however, with his TV show The Finder bombing after just one season earlier this year. The Fox series was a spin-off of Bones, but failed to wow.

In July, Michael suffered a heart attack and remained in intensive care for several weeks after.

TMZ originally broke the story that Michael's 38-year-old girlfriend performed 'heroic CPR and re-started' the actor's heart at his LA home before he was rushed to the hospital.
'Everyday GOD continues to smile upon my luv Michael Clarke Duncan on this arduous road to recovery,' Omarosa tweeted last month to her 30,000 followers.

According to TMZ, 'an army of people' were caring for Duncan, who was 'breathing above the respirator' and had a 'very strong heartbeat' after initial tests were performed on him.
Kent Moran, who directed Duncan in The Challenger, told MailOnline the actor recently wrapped on the action drama, in which he plays a trainer helping to revive the career of boxer Jaden Miller.

He added: 'We were very surprised and saddened to hear the news. Our film is now in post production and we have finished filming Michael's scenes.
'So at this point, we are really just praying for him and wishing him a speedy recovery.'
