From John Mayer to Orlando Bloom - and let's not even go there with Russell Brand - Katy Perry has a history of being drawn to men who are all neckscarves, poetry and ego. It's like she never quite got over every kooky high schooler's fixation with artsy, brooding heartbreakers. If My So Called Life's Jordan Catalano was real, Perry would have been all over him. Until now, that is. At first, the thought of Perry, 40 - a woman who once dressed as a burger for the Met Gala - dating former Canadian Prime Minister Justin Trudeau sounds utterly preposterous.
