Minnelli Sex and the City storyline 'a hoax'
Details of the film's top secret plot appeared to have been leaked in recent weeks, with sources insisting the two divas would appear in a ceremony uniting Cantone's character Anthony Marantino and Willie Garson's Stanford Blatch.
Minnelli herself told an Australian newspaper she performed a version of Beyonce's Single Ladies (Put a Ring on it) for the film.
But Cantone insists the rumours are false - hinting they are part of a deliberate ploy to throw fans and the press off the scent.
The actor tells NYPost.com's PopWrap blog, "No, nothing's true. I hadn't even read that. That's hilarious."
And he laughs off the suggestion of a Minnelli cameo: "No, I would have self-combusted! I would have been dead. I wouldn't be here talking to you. I don't even know that she's in the movie."
