Pimp my...cup? Rappers like Ludacris, Juvenile, and Nelly delight in custom-blinged goblets from Chicago-based Deborah Harrison (a.k.a. Debbie the Glass Lady), who crafts the vessels some for upwards of $1,000 from glass, diamonds, crystals, gems, platinum, and 24-karat gold. Lil Jon, who displays his ''pimp cup'' in the ''Get Low'' video, takes his chalice (in a one-of-a-kind padded carrying case, of course) to clubs. It's just the thing for swigging ''crunk juice,'' a sugary blend of his CRUNK!!! Energy Drink and Hennessy. And the love is spreading to non-rappers: The East Side Boy recently had cups made for Paris Hilton and Jessica Simpson, because, he notes, ''crunk juice makes the girls horny.'' How sweet.
