The statuesque blonde star had turned on the style in the stunning floorlength backless frock at the European premiere of Transformers 3: Dark Of The Moon in Berlin today. The 24-year-old supermodel-turned-actress had accessorised with a simple pair of diamond stud earrings and a sideswept, gently-waved hairdo to keep the look timelessly classy.

Earlier this week, Rosie was working it at the Moscow International Film Festival in Russia in a stunning Gucci frock with a see-through skirt, as well as a thigh-slashed hot pink maxi dress.
