While American Idol contestants Adam Lambert and Kris Allen were duking it out onstage, Simon Cowell and Kara DioGuardi fought at the judges' table.

Here's the thing: Adam and Kris are both completely talented singers in completely different ways... so it's always more fun to watch the judges go at it! Simon gave the first round to Kris and the second to Adam, but what about the third when they both sang "No Boundaries" (co-written by Kara)?

Meanwhile, Anthony Hopkins and Katie Holmes watched from the audience and Carrie Underwood performed at the end of the night. Did you vote?!? And who's a better judge - Simon or Kara?
