(digitalspy.co.uk) - Naomi Campbell has argued that the supermodel tag is used "too loosely".The veteran model claimed that only Brazilian Gisele Bundchen has matched the standards reached by Kate Moss and herself during the 1990s."Models need to earn their stripes - I just think the term is used a little too loosely," she told The Sun."Kate Moss is obviously a supermodel but, after Gisele, I don't think there's been one."
