VIDEO : MTV Halts Productions On 'Catfish'

(CNN)MTV has put production of its reality series "Catfish" on hold as host and executive producer Nev Schulman faces allegations of sexual harassment. "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." The investigation comes days after a former guest on the reality show posted videos on YouTube, alleging she was the recipient of sexually charged language and that she was repeatedly asked about her sexual orientation. I have always been transparent about my life and would always take responsibility for my actions -- but these claims are false."
