It doesn't quite rank up there with "Either those curtains go or I do," but some of the last words of a deceased mobster may go down in their own kind of infamy: Tom Cruise is straight.

A new biography of the deceased con artist, jewel thief and art forger Johnny Fratto sees the former mobster recall his experiences coaching Cruise for his role as a pool hustler in 1986's The Colour of Money. And while Fratto remembers Cruise being impressed by his criminal past, he also insists that the star is entirely heterosexual.

"Despite what rumours you've heard, I can vouch from firsthand experience that Tom Cruise is not a homosexual," Fratto states.
