Katy Perry went for a cheeky peekaboo dress, with little slashes all the way down the front. The slashes revealed glimpses of cleavage and tummy button, and were generally much more daring than anything in our wardrobe.

But once this latest round of promotion for the film is over, Katy has promised she'll be taking a holiday.

"I have to say that I do a lot to sell my records," she said. "I do the right things… I work very hard! I like to sell out in all the best ways."
