American Idol was hit with a historic TV upset Tuesday Night after ABC’s ‘Dancing with the Stars’ competition pulled in higher ratings than ‘American Idol’.

Dancing scored a 16.5 rating/25 share to Idol 16.3/25, in what insiders are calling a ‘photo-finish’.

The upset comes as the nations top-rated show experienced viewership erosion late in the season, at one point falling more than 15% from a year ago.

Simon didn’t look the same last night. He seemed bored, going through the motions, as he slightly criticized the karaoke singers.

Looks like Simon checked out a couple of weeks ago along with the rest of audience.
