Katy Perry’s Sexiest On-Stage Outfits
Katy Perry performs in Sheffield, UK on October 12, 2011. Katy invited guests up onto the stage to dance with her before releasing giant beach balls into the crowd then devilishly soaking her fans with a giant foam gun for her grand finale. She joked 'I have a little British in me. Well, every other night maybe' as she gushed with excitement about being back in the country.
