Production of MTV’s show Catfish has been suspended due to sexual harassment allegations against the show’s host Nev Schulman. Last week, Ayissha Morgan, a former participant of the show made a YouTube video claiming she was harassed.

Morgan posted two videos titled “The TRUTH about the show” stating, “Jack,” the pseudonym she gave the show’s “main person,” approached her several times, asked her if she was really a lesbian and told her he had a large penis.

MTV said in a statement, “We take these allegations very seriously. We’re working with Critical Content, our third-party production company, to conduct a thorough investigation and we’ve put a pause on shooting until the investigation is completed.”

Schulman went to USA Today to deny the allegations, “The behavior described in this video did not happen and I’m fortunate that there are a number of former colleagues who were present during this time period who are willing to speak up with the truth. I have always been transparent about my life and would always take responsibility for my actions — but these claims are false.”
