After touching down in Paris rocking an outfit that would make Lilo proud, Katy Perry slipped into something a little sexier when we snapped her leaving the Plaza Athenee Hotel. The songbird is in Paris to promote her new album Teenage Dream, and she's fresh from a stint as a guest judge on The X Factor in London, so it looks like she's completely booked!

Just hours after she landed in the city of lights, Katy tweeted, "Drank Jean Paul Gaultier water & used pink rose scented bathroom tissue! Oh frenchies, you are TRES CHIC!" Yeah, what she said!
