Here’s Katy Perry doing what she does best (and the only thing that we actually enjoy and want her to do) on “The Tonight Show with Jay Leno” the other night, and that’s dropping a massive amount of cleavage action. And… yup, said cleavage is still super ginormous and drool-inducing as all hell. Especially in shwingtastic motion in the video bellow. Hot damn is it ever! Enjoy!
