Katy Perry runs Art Museum steps

Last night, Katy Perry tweeted: 

Her promise? To head to the steps of the Philadelphia Museum of Art, where she meeted and greeted with fans while wearing a sweet pizza-themed onesie. Duing her Wells Fargo Center run, Perry gave away a pizza onstage to a lucky fan (although, Ms. Perry should not be eating pizza. As she said onstage, she's allergic to gluten.)

Look at her Hugh Jackman-looking bodyguard

And now we have video!:

My buddy HughE Dillon has some excellent pics of the mob scene, along with some hilarious fan shots, over at PhillyChitChat.
