In 2017, Barth revealed that she was a victim of sexual harassment from
Harvey Weinstein in 2011. She met with Weinstein in her hotel room as he "alternated between offering to cast her in a film and demanding a naked massage in bed''. The same year Barth claims
David Guillod drugged and sexually assaulted her in 2012 when he was working as her manager. She told
Seth MacFarlane about the incident with Weinstein and MacFarlane took the opportunity to insult him while presenting the 2012 Oscar nominees with
Emma Stone.
