Keira Knightley and Dominic Cooper popped in to the Radio One studios yesterday, ahead of The Duchess's premiere in Leicester Square this evening. Keira accessorised her monochrome outfit with an animal print scarf and cute heels, while Dominic gave us a glimpse of that chest we saw in all its glory in Mamma Mia. From what Dominic said about his costumes (or lack thereof) on set, I'm fairly confident he wasn't wearing a skin-coloured nappy under that casual outfit.
