You never know who the next Black AMEX cardmember will be. It is no secret that Hugh Hefner’s “Girls Next Door” from the show on E! are all packing the Black Cards in their Prada bags. Hef’s three pampered girlfriends Kendra Wilkinson, Holly Madison (his girlfriend no longer as of October 2008), and Bridget Madison are regulars at the Joseph Martin Salon in Beverly Hills where they get their hair bleached to that platinum blond. But money is no problem there or anywhere else on Rodeo Drive when you have a black card.
