Hef and girlfriend Holly Madison show off the panty chandelier.

The party posse surrounds Hef on the bed.

Hef himself docents the home and garden tour for the special sixth season premiere of MTV's documentary series. For the full half-hour, Hef's rare, all-access tour of the Mansion allows MTV's cameras into his private bedroom (where we find a Coyote Ugly-inspired panty chandelier) and the adjoining antique bathroom with a party-size marble tub. Hef leads the cameras up the spiral staircase from his bedroom to his rarely seen attic electronic center where he keeps his extensive color-coded tape library and an impressive state-of-the-art editing suite where 11-year-old son Cooper, an aspiring filmmaker, is cutting his own movie.
