The model-turned-actress was displaying a serious expanse of thigh at the Cartier International Polo yesterday.

Prince Charles was overseeing the event in place of the Queen, apparently channelling James Bond in a pair of dark glasses and a suave white blazer.

Many of the celebrities had sought shelter in the marquee, missing out on the polo - and on the streakers. Three men ran on to the turf during the match between England and Australia, to cheers from the crowd.
