Movie producer Harvey Weinstein has claims he brokered the lucrative deal with an unnamed Middle Eastern Prince, who wanted to meet the 'Twilight Saga' star, 23, in order to raise money for the Hurricane Sandy relief fund last year.
He told reporters at a screening for the new Hurricane Sandy benefit concert documentary, '12-12-12', at the Toronto International Film Festival on Sunday that the brunette beauty agreed to sit and talk to the royal for 15 minutes in exchange for a substantial donation to the Sandy relief effort.
The wealthy prince reportedly paid the sum in cash up front and then met with Kristen briefly at Madison Square Garden in New York.
According to the New York Times, Harvey said: "And Kristen sits with the guy for 15 minutes."
The movie mogul rallied dozens of his other high profile friends to take part in the Hurricane Sandy benefit concert last summer, including The Rolling Stones, Kanye West, Paul McCartney, Billy Joel, Chris Rock, Adam Sandler, Mick Jagger and Bruce Springsteen.
The event raised $65 million dollars for the Robin Hood Foundation to benefit victims of the storm.
Harvey believes the new documentary shows a perspective of the concert that fans didn't get to see.
He said: "That's the only reason to make it."
The film is expected to be released to mark the anniversary of the super storm, which battered the northeast coast of the US, on October 29 and will be premiered in New York.
