"Mary was traumatised and became deeply depressed," the suit states.
"Mary would become extremely nervous and anxious whenever, among other triggering events, she hears any mentions of [the] song and [the] song itself, whenever she ruminates about the events during or related to the performance, and whenever she thinks about the prospective televised airing or use online of Jane and her husband, their performance, as well as the airing and use online of any footage of Mary."
The suit alleges the production company got Mary to sign a contract without her parents' knowledge or consent, and is claiming damages for infliction of emotional distress.
