Jurassic Model a Tyrant-osaurus on HSN

There are two constants in life -- Home Shopping Network hosts can get excited about everything and Janice Dickinson is a bitch.

TMZ sources say that flamboyant Home Shopping Network host Adam Freeman and the entire HSN staff have major haterade for all things Janice after she showed up to hawk her jewelry line acting like, well, Janice.

We're told Dickinson told Adam backstage he needed to lose 20 lbs. and that she was extremely rude to employees who originally were excited for her presence.

The water cooler conversations in HSN's offices this week have revolved around the "We hate her and are very disappointed" standpoint.

No surprise there.
