Oprah Winfrey's OWN network has been hit with a sexual harassment lawsuit by a woman who claims she was humiliated by her female supervisor.

The plaintiff also claims that she was harassed based on her pregnancy.

In the lawsuit filed in Los Angeles Superior Court on Wednesday, Rebecca Taylor claims that she came aboard OWN in November 2010, only to suffer a string of harassing incidents at the hands of her supervisor Nakisha Gowen.

Among the alleged offenses, according to the suit: Gowen interrupted Taylor's breast-pumping session while Taylor was in OWN's designated pumping room by knocking loudly on the door, when she could just as easily have emailed or called Taylor.

Taylor also claims that Gowen would "discuss sexual topics in company meetings" in Taylor's presence, reenacting sex scenes from horror movies in graphic detail.

The suit goes on to claim that Gowen sexually assaulted Taylor at a company meeting by "simulating that she was squeezing Plaintiff's breasts," leaving Taylor "mortified and humiliated."

A spokeswoman for OWN has not yet responded to TheWrap's request for comment.

The lawsuit claims that, because of the ordeal, Taylor "suffered panic attacks, she could not sleep and she began crying at work."

Alleging sexual harassment, sexual discrimination and pregnancy discrimination, among other counts, the lawsuit seeks unspecified damages.
