Katy Perry was supposed to make a stylish guest appearance at friend Jeremy Scott's debut fashion collection for Moschino at the Milan Fashion Week but it turned unpleasant. Ms Perry made the crowd wait for 50 minutes so the upset fashionistas and photographers at the event booed the "Roar" singer off the catwalk for her behavior.

According to the Mail Online report, the Autumn/Winter 2014 show that will display the American fashion designer's first collection at the Corso Venezia has been scheduled to start at 8 pm last Thursday, February 20, but it has been delayed until Katy Perry finally arrived at the event.

The 29-year-old singer had a brief photo shoot on the catwalk in her black and gold dress and coat but the crowd booed her off. "You're all going to get your picture, so shut the f**k up," Ms Perry stated to the crowd in the News.com.au report but the embarrassment made the singer immediately head towards her seat before the lights dimmed for the fashion show.

An unnamed onlooker at the Moschino show revealed to Us Weekly that Katy Perry was "upset over the incident" while an insider claimed that the singer was given the instruction to come at that time. Meanwhile, the people who were not impressed with Katy Perry's tardiness included the Editor-in-Chief of Marie Claire UK, Trish Halpin and the fashion editor for the Financial Times, Vanessa Friedman.

Both Ms Halpin and Ms Friedman shared what happened at the fashion show and expressed their opinion about it on social networking site Twitter. Another guest celebrity attacked for arriving 45 minutes late at the event was Katy Perry's friend and fellow pop singer Rita Ora.

The Moschino event is the first time for designer Jeremy Scott to showcase his fashion designs for the house. Mr Scott, who got appointed as the creative director last October 2013, has included the knitwear emblazoned with an image of cartoon character SpongeBob and a sweater riffing on McDonald's golden arches with the iconic slogan "Over 20 billion served" in his creations.
