Katy Perry really looks like a mannequin especially when wearing her signature make-up style. In her latest performance, Katy seems to be rocking the stage once again with her heart-pounding and head-banging music. The mini red polka dot dress accentuated with a red heart belt embraces the curves of the young Hot and Cold singer. Katy Perry seems to like high-waist garments a lot. If you can remember, we have featured her a few days back in her high-waist swimwear while having some fun with Rihanna in Barbados. But then, despite of that, Katy still looks pretty and cute especially when she started to get wild on stage.
