Seacrest Twitters ‘Idol’ secret

Host tells who was voted off before West Coast b'cast

This… is not what “American Idol” producers or Fox would’ve preferred.

At 8:43 p.m. — before Wednesday’s show even began — “Idol” host Ryan Seacrest told his 3 million-plus Twitter followers that Lacey Brown was eliminated and the contestant field had narrowed to 11. He used the tweet as a promotion for his early morning radio program that’s syndicated around the country.

“Packed radio show tomorrow…got tonight’s voted-off idol lacey brown,” wrote Seacrest, who taped the reality behemoth from 6-7 p.m. at the CBS lot in Los Angeles.

The ill-thought move had ramifications. While Fox easily won the primetime ratings race and “Idol” was the most-watched show, competition was extremely weak, consisting mostly of repeats.

The 6.6 rating in the 18-49 demo was lowest among regularly scheduled “Idol” broadcasts in the show’s history.

Twitter users began reacting immediately to Seacrest’s post, and negative reaction continued Thursday.

Neither “Idol” producer 19 Entertainment, Fox, nor Seacrest would comment.
