I know it may shock and appall my many readers who’ve applauded Katherine Heigl’s courageous decisions to bash the movie that made her famous and insult the writers of her show, but apparently, having her on a movie set isn’t exactly sunshine and cockrings, if you catch my drift.

According to one extra [always sources of accurate and unbiased info] who was on the set of “27 Dresses,” Heigl “reportedly refused to film any scenes until her pregnant assistant ran around and got her a Coke Zero. She refused to eat lunch next to anyone or have anyone speak to her once the cameras stopped rolling.”  According to another insider, “No one on the crew likes her.”  Another source added that “many directors that she’s worked with in the past do not want to work with her again.”

On the set of her latest movie, “Five Killers,” [Heigl] has been “extremely unprofessional,” “flaking on meetings and making ridiculous demands,” insiders say.  Heigl reportedly has insisted that she be flown by private plane to the film’s international locations and wants “crazy amounts of security.” [NYDailyNews]

Well look, when you’re the star of films like 27 Dresses and… uh, 27 Dresses (the only movie she did last year), you can get away with a few extra demands.  And in her defense, one of Five Killers‘ filming locations was Rapetown, South Africa.
