The model was snapped as she filmed scenes for her new movie Taking Stock in London yesterday (1 July).
Despite her celeb bank balance, Kelly championed the high street in a vibrant floral frock costing a purse-friendly £22.99 from New Look.
The brunette beauty accessorised her tanned legs with stacked strappy sandals, keeping her Ugg boots on hand for a comfier option between takes.
We're definitely not loving the boots and dress combo, though!
