It looks like Katy Perry loves pizza just as much as the rest of us — she wore a pizza-patterned onesie last night when she met fans at the Philadelphia Museum of Art after her concert. Perry has never been shy about her love for pizza, as she posted a photo of herself eating her own personal pie just a few weeks ago.

Then there was the pizza-themed swimsuit and matching pizza slice earrings that made an appearance in her new video for "This is How We Do." And that time she frightened her dog in this adorable (and strange) Instagram video.

It may only be August, but we're feeling potential Halloween costume ideas coming on here.

UPDATE: Cara Delevingne has taken a page out of Katy Perry's book and decided to show off her same affinity for pepperoni pizza. Are you hungry yet?
