Kate Bosworth and Michael Polish at the Airport

Kate Bosworth arrived at LAX hand in hand with fiancé Michael Polish yesterday. Kate and Michael returned to the West Coast after a busy week in NYC, where they attended many shows and events for NYFW. On Monday, Kate and Michael sat front row at Theyskens' Theory, and last week she stepped out solo to celebrate the opening of Proenza Schouler's store with designers Jack McCollough and Lazaro Hernandez. At the bash, Kate interviewed Proenza Schouler's Jack and Lazaro, too. Her and Michael's stay wasn't all about fashion, though, since they visited Ground Zero on Tuesday in honor of the 11th anniversary of 9/11.
