Reality TV news site, Gold Derby, broke down the network's audio leak with some juicy insight.

According to the site, Christie Murphy was unveiled as the first HoH (aka Head of the Household) for Season 21. In the clip, the reveal was brought to light when a group of women were talking, and there was a knock at the door.
