is calling out the Australian paparazzi.
On Nov. 21, she shared a message that she was "stalked by many grown men" when she was trying to take a quiet walk on the beach.
She says these paparazzi "have no respect, no integrity, no character and NO HUMANITY."
The 30-year-old pop star then turns the tables on them and posts their pictures.
Perry doesn't stop there as they apparently got photos of her in a bikini, and she wants everyone to know that those pics are not approved by her to publish.
She then calls out Australian paparazzo Jamie Fawcett saying, "Ur a true sicko for taking pictures of us while being naked."
However, Perry did post her own bikini photo as she posed on a yacht before she climbed Sydney's Harbour Bridge.
Perry is currently on her Prismatic world tour
and has been performing in Australia since Nov. 7. After she wraps her concert in Brisbane on Dec. 15, she will head to New Zealand to perform just five days later. She will kick off the new year in February with her European portion of the tour in Barcelona.
