>> Is Renee Zellweger's Red Carpet Partnership with Carolina Herrera Over? —Last week, sources told WWD that Mario Grauso, president of Puig Fashion Group who oversees Carolina Herrera, Nina Ricci, and Paco Rabanne, has submitted his resignation and will step down after New York Fashion Week.  The exit is said to be amicable, but it is speculated that he was unhappy with Olivier Theyskens's ousting at Ricci.  Now, a source tells Page Six, Grauso, who introduced Renee Zellweger, Amy Adams, and Reese Witherspoon to Carolina Herrera, may be taking his celebrity followers with him: "None of them will wear Carolina Herrera on the red carpet now that he's gone. Mario paved the way for the brand by putting Renée in Herrera for award shows and carpets. He made it youthful." [WWD, Page Six]
