Last week, rumors surfaced that Puig Fashion Group president Mario Grauso will step down after September Fashion Week. Now rumors are swirling that his celebrity friends may join him in abandoning Puig, which owns Carolina Herrera. Grauso introduced Renée Zellweger, Amy Adams, Reese Witherspoon, and Mariska Hargitay to the label, but if he goes, they might not wear it on the red carpet anymore, insiders say. Renée pretty much wears Carolina exclusively on the carpet. What is she going to do? Go naked?! [NYP]
