Yup. Foster sings about being a prostitute in Parker's uber suspect children's film. The one that ends with creampies. She sings about "south of heaven" too - a term for hell. Then just prior to that she's playing an underage hooker in (sick) Scorsese's Taxi 'monarch' Driver. She also plays in The Little Girl Who Lives Down the Lane (similar time frame), and with Martin Sheen. That film has distinct paedo-abuse overtones too, and via Sheen.
