Katy Perry is a tropical dream in Times Square yester day as she introduces the new Volkswagen Jetta in a palm-tree-patterned latex dress.

Earlier this week, Perry — who’s engaged to British star Russell Brand — celebrated the US-Brit ain World Cup match by wearing a red, white and blue latex dress.
