Mariah Carey is developing a new fake tan made with 24-karat gold dust. The singer is insisting she is beautifully bronzed on every night on her current 'Emancipation of Mimi' tour and has hired a personal tanning assistant, Jenny Phillips, to spay her before going on stage. Mariah and Jenny, of Beverly Hills' exclusive Portofino Sun Center and Spa, have now teamed up to create an extravagant new fake tan made with real gold. Mariah's representative said: "She is on tour with Mariah and they are developing an exclusive line of bronzer containing real 24-karat gold dust." The 'We Belong Together' singer is famous for her outrageous diva demands and extravagant tastes. In the past, Mariah has paid for her Jack Russell dog - named Jack - to fly first class, refused to walk up or down stairs, requested a red carpet be rolled out for her arrival at a London hotel and reportedly demanded toffee.
