Last week we brought you pictures of Liz Hurley vamping it up in a figure hugging red dress on the set of Blake Lively who was spotted sporting this maxi skirt.
Blake swapped the black leggings and white tee she wore to work for Serena's boho ensemble - although she kept a tight grip on her own iced coffee!
Our only issue with the look is the flip-flops. They're a world away from the towering heels we've grown used to seeing Blake in during her summer of Green Lantern photocalls and Chanel brand ambassadoring and even though we're fans of our comfy flats, these look a bit ratty.
Let's hope they belong to Serena's wardrobe and not to Blake!
