This past week was the first episode of this season of American Idol.  With J-Lo and Steven Tyler now judges, are you watching?

Ratings for American Idol's season ten premiere dropped 13 percent from last year. Entertainment Weekly reported that the revamped debut attracted 26.1 million viewers.

In the key adult demo, 18-49, ratings were down 18 percent. That number represents the lowest-rated premiere for Idol since its 2002 summer debut and the biggest drop ever for the show between seasons. The previous record-holder was 2009's premiere, when the ratings fell 15 percent.

Entertainment Weekly noted that Fox insiders weren't going to panic unless the ratings dropped more than 20 percent.

* It will be interesting to see Thursday's ratings, as the show is expected to face stiffer competition on the new night.

* Meanwhile, the new judge's panel got fairly good reviews -- especially Steven Tyler who called "a marvel." CBS agreed that he is the "early fan favorite."

* In other news, the Idol premiere crushed Paula Abdul's Live to Dance, which drew only 5.3 million viewers.
