January 28, 2008 -- RUSSIAN model Natalia Vodianova, 25, retired from the catwalk last week after walking in Valentino Garavani's final show in Paris. To celebrate, the mother of three is taking Valentino to Moscow for a week and then to Brazil for Carnivale. "She may do another show in the future," said a source, "but only for $500,000 or this large pink diamond she's had her eye on." The night of Valentino's last show, his longtime right-hand man, Carlos Souza, also retired, and his head of public relations, Annelise Peterson, left to join Alberta Ferretti next month.
