Katy Perry took to Twitter on Saturday to unleash her frustration about being stalked by paparazzi while hitting the beach in between concerts on the Australian leg of her Prismatic world tour.

Katy Perry Takes Paps To Task

“Australian PRESS: You should be ashamed of your paparazzi & tabloid culture. Your paparazzi have no respect, no integrity, no character. NO HUMANITY,” Perry wrote in a note she posted to Twitter. “I was stalked by many grown men today as I tried to take a quiet walk to the beach. These men would not stop as I pleaded over & over to let me have my space. Many other people stopped to try to help but the paps continued to laugh at me & hold their barrels up & shoot.”

“They told me to make a ‘deal’ with them. Give them a bathing suit shot and they would leave me be,” she added. “This is PERVERTED & disgusting behavior that should NEVER be tolerated, especially by people who do NOT want this. I will NEVER make a deal with paparazzi and I will not befriend anyone who perpetuates this kind of behavior.”

Later on, Perry posted a photomontage of some of the men who were photographing her against her will.

The pop star also warned Australian publications about publishing the pictures – pictures that she did not want taken – and singled out paparazzo  Jamie Fawcett.

Perry will continue touring Australia through mid December. She’ll then play two shows in New Zealand. Starting in February, she’ll begin the European leg of the tour, which will include stops in Spain, Germany and Sweden.
