Kristen Stewart at Balenciaga Paris Fashion Week

Kristen Stewart stepped out in Paris today to attend Balenciaga's Fashion Week runway presentation. As the face of the brand's fragrance, Kristen was expected in the front row for the show and posed with Salma Hayek before taking her seat. Kristen arrived in Paris yesterday and stepped up her sexy factor for this afternoon's event. Kristen's arrival in Europe comes amid good news for fans following her personal life. Robert Pattinson and Kristen have reportedly moved back in with each other following their rocky Summer. It would be good timing for the couple, who will be spending a lot more time together when their Breaking Dawn Part 2 press tour kicks off soon.
