A male model who worked with Katy Perry on her “Teenage Dream” music video has accused the singer of pulling down his pants and exposing his genitals to a group of people at a mutual friend's birthday party. Josh Kloss went public with the allegations against Perry on Sunday, in what he said was the anniversary of working the music video job, in a post shared on Instagram. The incident, however, is said to have occurred sometime later at costume designer Johnny Wujek’s birthday party, sometime after Perry split with ex-husband Russell Brand in 2012. “I just say this now because our culture is set on proving men of power are perverse. But females with power are just as disgusting,” Kloss wrote on Instagram on Sunday. “So, happy anniversary to one of the most confusing, assaulting, and belittling jobs I’ve ever done. Yay. I was actually gonna play the song and sing it on ukele for the anniversary, but then as I was turning I thought, f**k this, I’m not helping her bs image another second.” After coming forward, Kloss was questioned as to why he waited so long to speak out, which Kloss said was because he was traumatized at first, and later wanted to wait until it would not be confused as an effort to seek financial gain but felt he needed to make people aware of what he implied was her abuse of power. Kloss wrote in an Instagram story post shared on Sunday, after his initial announcement, about how difficult coming to terms with what he said happened has been for him. “To admit that someone violated you in such a f**ked up way, and you didn't call the cops at that moment was hard to swallow, and it took a lot of time,” he said. “There have been a million times I could have brought it up, but those times would have benefited me financially. At this time there is absolutely no benefit for me, but benefit for many others, who can contemplate power, would they do what she did to me, or would they stay respectful of me and my body. So you believing me is inconsequential to me, it's more about letting people believe that even a guy like me has felt powerless and been violated, and still courageous to bring it up when it counts, not when it's lucrative.” In an Instagram video posted immediately before the statement, Kloss acknowledged how grateful he was to be cast opposite Perry as her love interest in the Teenage Dream music video which came out in 2010, but said he has no loyalty to the singer.
