YouTube sensation Sam Pepper faces rape allegations from an anonymous 20-year-old Toronto woman who alleged he forced himself on her in April 2013, Buzzfeed reported Saturday. She told Buzzfeed she met Pepper April 26 while he was on tour with rapper Sammy Adams and singer T. Mills.

“I didn’t even know who Sammy Adams was,” she said. “I just went because my friends, we all really liked that whole YouTube thing at that time and my friends told me about [the concert] and said that [Sam Pepper] would be there.”

When the former U.K. “Big Brother” tweeted he was in Toronto, the woman, her friend and her older sister exchanged information with him on Facebook, the anonymous woman said. He asked if she would come to his room at the Westin Hotel and promised he would get her backstage if she did. She agreed.

“I walked into his room. He was sitting on a queen-sized bed watching TV,” she said. “There were two beds in the room, and I had no interest in lying next to him on a bed, so I sat on the other one and began to talk to him.”

He tried to lift up her shirt and pull down her pants once she sat on the bed, she said. “The most I could blurt out was ‘Well, I can’t have sex with you. Please don’t have sex with me. I don’t do this kind of thing,’” she told BuzzFeed. “Which was true, at this point in my life, I had never done anything like this with a boy.”

Then the anonymous woman, who was 19 at the time, said Pepper forced her to perform oral sex. “He continued to do things to me against my will and then forced me to give him head, nearly choking me,” she said. “Afterwards, he threw me a napkin and told me that it was time to go.”

The woman said she didn’t report Pepper because she didn’t realize the gravity of the situation. “I thought it was my fault,” she said. “When I found out that he did it to other people, it felt like a sock in the face.”

The allegation comes a week after Pepper posted a “prank” video that shows him groping and pinching women on the street, MTV News reported. He claimed the women were in on the “social experiment” where he asks them for directions and then feels them up with his hands hidden beneath a large sweatshirt.

But it appears his private dealings with women are far from a joke. Multiple women have accused Pepper of inappropriate touching or interactions. He was also accused of soliciting nude photos from an underage girl.

Pepper has not responded to the allegations, Buzzfeed reported after they tried to get in contact with him. He apparently deleted his Tumblr, Facebook and Instagram pages Friday.
