The biggest diva on a new network show this year might not actually be Katherine Heigl. This B list mostly television actress, who also does some movies is getting another shot at network television in a lead role and has been making life miserable for the production assistants on the shows. Prepare for the wrath of our actress if her tea, two bags, with exactly 1 1/2 cups of water is not the proper temperature. The screaming can be heard throughout the entire set. Hair not up to her level? Well, two hair people have quit because of her tantrums and “suggestions.” Our actress also can't walk from her trailer to the set even if it is 25 feet. She needs a golf cart and she needs at least two, preferably three people to accompany her to make her feel even more important.
