Hugh Hefner has been photographed on numerous occasions wearing silk pajamas, sometimes with a smoking jacket worn over them. Reportedly, Hefner prefers pajamas to regular clothes and only wears them (or nothing at all) when he is at his estate, the Playboy Mansion. Hefner owns several hundred sets of pajamas, enough to last him years without repeating a single set if he were to change into one every day.

The reality television show The Girls Next Door depicted Hefter and his three live-in girlfriends, Holly Madison, Kendra Wilkinson and Bridget Marquardt. Since the conclusion of the fifth season, the girls have left the mansion, some with their own "spinoff" shows. The show will continue to air, it's sixth season revolving around Hef and his new 19 year-old twin girlfriends, Karissa and Kristina Shannon; and 23 year-old, Crystal Harris. http://www.nydailynews.com/gossip/2009/01/06/2009-01-06_meet_playboy_founder_hugh_hefners_other_.html
