>> Natalia Vodianova walked a couple of shows in Paris last week (Givenchy, Hakaan), sat in a few more front rows (Louis Vuitton, Valentino, Stella McCartney, Christian Dior), and even found the time to run the Paris half marathon for her Naked Heart charity in between. Her three children accompanied her front row to Stella McCartney, but her husband, Justin Portman — to whom Vodianova has been married since 2001 and who usually pops up wherever she is — was nowhere to be seen. The couple has been plagued by rumors of separation recently, and sources tell Page Six they have been spending less time together; Portman was reportedly at their house in Uruguay during the shows. Vodianova's rep, meanwhile, says: "They are still married. She is traveling and very busy with her career." [NY Post]
