It’s a Katy Perry Post

Hopefully by now everyone should know what to expect whenever the name Katy Perry appears in the headline. But just in case, she was at some thing, singing some song, big, giant breasts. That’s literally all you need to know. If anything at all, really.

Oh, and John Mayer looks at these and lights English muffins on fire. That, too.
