The duo bumped into each other following her divorce from Russell Brand.
“This one time I brought a friend who was dying to meet her,” he shared.
“It was Johny Wujek’s birthday party at Moonlight Rollerway. And when I saw her, 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.”
“Can you imagine how pathetic and embarrassed I felt? 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,” he wrote.
Josh divulged that he made $1000AU from his work with Katy.
Josh continued to share information from his experience.
“I was lorded over by her reps, about not discussing a single thing about anything regarding Katy publicly. And a couple interviews they edited and answered for me,” he said.
“So, happy anniversary to one of the most confusing, assaulting and belittling jobs I’ve ever done. Yay #teenagedream.
“I was actually gonna play the song and sing it on ukulele for the anniversary, but then as I was tuning I thought, f—k this, I’m not helping her bs image another second.”
Katy Perry is yet to comment on the allegations.
