Hilary Duff was spotted filming for Gossip Girl yesterday as she shot a scene with Penn Badgley. The couple seemed to be cosying up, but it's her arm candy which I can't take my eyes off. I love the funky green colour of her Mulberry Mitzy Hobo bag (£495) which looks great next to the floral dress. This is a great daytime bag as it's slouchy and big enough to carry everything. What do you think of this key Mulberry accessory?
