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

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 and the only program to garner more than 10 million viewers — competition was extremely weak, consisting mostly of repeats — the 6.6 rating in the 18-49 demo was one of the lowest in “Idol” history.

Twitter users who watch the show while tweeting at the same time time began revolting immediately when reading Seacrest’s post, and negative reaction continued Thursday. Neither “Idol” producer 19 Entertainment, Fox, nor Seacrest would comment, and Seacrest never apologized on his Twitter feed.

Of course, those West Coasters who can’t bear to wait until 9:55 to find out who was eliminated can always Google away, but Seacrest’s move to benefit his radio show at the expense of “Idol” couldn’t have played well with Fox.
