Grey's Anatomy star Katherine Heigl had a screaming hissy fit on the set of the hit show, sources have told The National Enquirer.
The 27-year-old blonde plays sensitive intern Dr. Isobel "Izzie" Stevens on ABC's hot medical drama — but insiders say the real Katherine is very different from her TV character.
"Katherine thinks she's a huge star, and entitled to throw disruptive diva fits at the slightest provocation," claims an insider.
"The other day she was driven from her trailer to the set a half-hour before she was needed, and you'd think someone had beaten her over the head.
"We heard some blood-curdling screaming, and my first thought was that it was in the script, a patient dying in agony. But I was astounded to see Katherine yelling at the top of her lungs."
The insider says cast members' trailers are a half a mile from the set, and the actors are driven in a golf cart when they're needed.
"It's not as if she had to walk, like crew members and extras, or that it was raining. With the money she makes, you'd think she wouldn't mind waiting around a few minutes until they needed her.
