Actress Ellen Pompeo, who plays Dr. Meredith Grey, on the hit TV show Grey’s Anatomy is turning everyone on the set against her with her diva behavior and belief that she is the star of the show.

According to insiders, Ellen — who portrays Dr. Meredith Grey on the smash ABC drama — has outraged fellow cast members and show producers with diva-like behavior and demands for more money and preferential treatment.

“Ellen’s become an insufferable jerk and her co-stars have really begun to resent her attitude and actions.”

“Just call her pompous Pompeo,” said a show insider. “She’s appointed herself the star of the series and has gone as far as to insist on separate interviews from the rest of the cast while on an overseas press junket.” Ellen’s arrogant attitude is getting on people’s nerves, according to the insider.

I was recently a part of a panel of Hollywood executives who debated Grey’s Anatomy. The biggest complaint from the panel was that Meredith was too whiney, bland, and predictible. Most on the panel implied that she was the weak link of the cast. If there is a true star of the show it would be McDreamy. Even George and Izzy are a whole lot more likeable than Meredith.

“Frankly, Patrick Dempsey is a much bigger star than Ellen ever will be. But even he doesn’t have the same kind of ridiculously inflated ego she has.”

Ellen is simply not a major Hollywood starlett no matter what she thinks or her advisors tell her.

Ellen also thinks her paycheck should be heftier than those of her cast mates, claims the source.

“I think she believes she should be getting the same kind of money that the Desperate Housewives stars make — in the $200,000-plus an episode range.”

Grey’s Anatomy could even survive without its character namesake.

“The show may be called Grey’s Anatomy, but that doesn’t mean the Grey character can’t be replaced. The show is a success because of the interplay of the large cast, not one actor in particular.”
