Christina Aguilera may have buried her ample assets in a -- gasp! -- PANTSUIT when she guested on ''Ellen,'' but you didn't think she'd really cleaned up her act, did you? The dirrty diva's a fan of Third Rail Jewelry's ''Stripper'' earrings. (''American Idol'''s Fantasia owns a similar, tamer version with her name in the hoop.) The bauble represents ''what happens when street meets fashion,'' says a company rep. Street corner, perhaps?
