Jessica Simpson lashed out on her twitter page after her sister Ashlee was fired from "Melrose Place" due to her utter and complete inability to act. Whatever, like Jessica totally isn't gloating on the inside that she's not the big failure for once.

The singer, 29, used to promote her sister's former show regularly on her Twitter ("Everyone watch my sis on melrose place tonight," she wrote Oct. 20). But on Sunday, she changed her tune drastically. Jessica wrote: "CW catching up on MP.who writes this crap?i have had bad scripts to work with,but this?thank God my sister is amazing and got you some press."

Ashlee, a veteran of TV's 7th Heaven, was canned because producers thought she couldn't act. "They hired her because they needed a good name to help create buzz," a set insider told Us Weekly. "But she was embarrassingly bad. Producers cut her down as much as possible." (Source)

I'm actually going to miss Ashlee Simpson on "Melrose Place." Watching her stunning failure at acting and the cute way she overdramatically bobbed her head as she said each line was the most unintentionally entertaining aspect of the show. But you know who is going to miss her the most? The other actors. Ashlee made them all look so good comparatively; just think how hard they'll have to work now that she's gone. Ashlee Simpson is basically the acting equivalent of the ugly girl girls bring to the bar to make themselves look hotter.
