Katy Perry was booed while walking the catwalk at Milan Fashion Week, and was reportedly "upset" about it.


Warning: foul language!

Perhaps Katy should have called up her modeling pals? Perry's runway moment was ruined as she was heckled during Moschino's Fall 2014 show in Milan. Wearing a gorgeous black and gold dress paired with a matching jacket, the 29-year-old "Dark Horse" singer was met with boos and jeers, reports E! Online . Perry reportedly delayed the start of the show by nearly an hour, causing the photographers in the front row to become understandably annoyed, reports The Mirror . In a video of the show, Perry can be heard saying, "You're all going to get your picture, so shut the f--k up," posing with her hand on her hip as the crowd boos louder. Katy was joined by fellow singer Rita Ora. Designer Jeremy Scott didn't seem bothered by the show, posting this Instagram picture:

The show came after a busy day for the singer, who celebrated the release of her "Dark Horse" music video.
