Crystal Harris signed `ironclad` prenup before marrying Hugh Hefner

Washington: Playboy mogul Hugh Hefner and Crystal Harris signed an “ironclad” prenup before they tied the knot on December 31, according to sources.

The source said that the 26-year-old Playboy model has not been added to the Hefner’s pre-existing will, as his estimated 43-million-dollar fortune is promised to his kids, the University of Southern California film school and a variety of charities, Us magazine reported. But Harris - who unexpectedly broke things off with Hefner in June 2011 just five days before their first planned wedding - has made peace with Hefner’s plan. ANI
