Looks like Katy Perry is back to her outrageous fashion choices after appearing to tone it down a bit in recent months, sporting a hooded pepperoni pizza-print onesie at the Philadelphia Museum of Art on Tuesday, August 5, 2014.

Causing panedomonium amongst her fans, Katy, 29, signed autographs while covering up in her food-themed frock.

Katy actually showed off the bizarre onesie in an Instagram video two weeks ago, writing "Killer pizza bruh."

In her latest music video for This Is How We Do, she also sports a pepperoni-print swimsuit and matching pizza slice earrings.
