FOX scored the #1 spot in the ratings for last night's American Idol with special guest judge, Shania Twain!

Idol dominated above the competition, with a 16.6 rating/24 share at 8pm.  Comparably, and completely unprecedented, was growth for Idol over the year-ago telecast (12.5/18 on Jan. 20, 2009) of 33 percent.  Never in the history of television has a tv show in it's ninth season posted gains this large from the year-ago period.

Way to go Shania!
