Katy Perry accused of sexually harassing male model by pulling at his underwear to expose his penis

Katy Perry has been accused of sexually harassing a model who starred in the video for her hit song Teenage Dream.

Model Josh Kloss, 38, made the allegation in a series of Instagram posts, claiming the pop star pulled at his underwear at a party in July 2012 to expose his penis.

He wrote: "When I saw [Perry], we hugged and she was still my crush.

"But as I turned to introduce my friend, she pulled my Adidas sweats and underwear out as far as she could to show a couple of her guy friends and the crowd around us, my penis."

He added, "Can you imagine how pathetic and embarrassed i felt?"

Kloss went on to claim Perry's handlers made it clear to him he was not to discuss the incident and he agreed to stay silent because he needed the video job.

He added he is speaking up now as 'our culture is set on proving men of power are perverse' but, he said, 'females with power are just as disgusting'.

Perry, 34, has not yet commented on Kloss' allegations.
