Tig Notaro knows a lot about Louis C.K. In fact, there's a scene in her Amazon show, "One Mississippi," in which a powerful man masturbates in front of a woman. There are numerous stories that the male character portrays C.K ... and Tig wrote the episode.
Louis C.K. is an Executive Producer on the show but in name only ... he has no real involvement in day-to-day production.
Tig has previously said that she had an incident with Louis before starting "One Mississippi", but never offered specifics. She told our photog she's solidly behind the victims.
