Now this is how you make a Fashion Week debut! Kate Bosworth casually flashed her square-cut solitaire from the front row of Carly Cushnie and Michelle Ochs's Spring 2013 show. The actress, who is engaged to director Michael Polish, ignored ring-coveting glances and snapped shots of the label's collection on her iPhone. For their part, the Cushnie et Ochs designers were thrilled to host the famous bride-to-be, tweeting, "@katebosworth, you are everything, thank you so much for coming."
