Mafia legend John Gotti's widow Victoria has been hospitalised, according to a U.S. report.

The late crime boss' wife, who will be played by Kelly Preston in her husband John Travolta's upcoming biopic of the mob chief, suffered a stroke last week (begs13May13) and her children are currently asking for privacy as they cope with their mother's condition.

Marc Fiore, the producer behind the much-delayed film Gotti: In the Shadow of My Father, has also declined to comment on her alleged health woes, telling the New York Daily News, "This is a personal family crisis."

Gotti has suffered two strokes in the last eight years and she underwent surgery in 2007 to treat a blockage in her brain.

Preston is set to portray the 70 year old in the movie, while the actress' real-life partner Travolta will play the convicted Gambino family boss, who died behind bars in 2002.
