"It was really Crystal's proposal and I thinking it was a great idea," the Playboy organizer tells Us Weekly. "The summit of it is, we don't require gifts. A lot of public are in need and the idea of generous to charity instead of giving gifts to us presently made sense."

The charities that Hefner, 85, and Harris, 24, liked include kids of the Night, an L.A.-based institution that's committed to ending kid prostitution; charity: water, a non-profit that aims to offer clean and safe drinking water to public in upward nations; and St. Jude children's Research Hospital. "No kid is denied treatment, and it's a amazing association," Hefner adds.
