PHILADELPHIA: It’s clear Katy Perry doesn’t eat too much pizza. But when it comes to fashion the 29-year-old pop star has gone crazy for the pepperoni pie — wearing the pattern on her onesie after her Philadelphia concert recently

And it certainly made an impact as hundreds of fans mobbed the star, reports Daily Mail.

They gathered after the singer made an announcement on stage, stating that she would come to the top of the Philadelphia Museum of Art steps to meet her fans.

However when Perry arrived to the museum after her second concert in Pennsylvania’s largest city the huge crowds meant many were left disappointed. In her latest music video, Katy dons a pepperoni pizza suit and matching pizza slice earrings.

And the junk food theme remains throughout the rest of the three and a half minute clip with animated ice creams, a watermelon slice and pizza dancing along to the catchy tune.
