She was flown to Tennessee to star in a video for country parody artist Cledus T. Judd. According to sources on set, she wasn't the easiest star to work with. One insider noted:
"She was extremely annoying to everyone on set and her crazy laugh scared all the geese off!"
What were the geese for? Guess we'll find out soon enough when the video hits the web.
In the meantime, we hope she stays away from the Xanax!
