Katy Perry was in London doing what she does best… showing off great cleavage! Oh wait, I meant she was performing! The singer has an interesting taste in clothes, but luckily for us they almost always show off what the good Lord gave her. And why shouldn’t she? Katy has become a hot pop icon recently and there is no doubt why. Katy has an amazing body, and she can sing well, too. If that is not enough, then I guess you will just need more proof. Thankfully, Katy Perry has just provided that and then some in these wonderful pictures!
