British supermodel Naomi Campbell, who was once fired from a modeling agency for being a "rude and impossible little madam," did little to improve her image during a brief news conference in Dubai yesterday. According to the Gulf News, Campbell, who showed up in the oil-rich United Arab Emirates to promote her new perfume, created a stink with local journalists when she arrived 90 minutes late for a scheduled news conference and then left after answering only four questions -- questions, it was pointed out, that were posed by her own entourage.
