Oops!  Adam Levine uttered under his breath, "I hate this country," into a hot mic on "The Voice" Tuesday night!  (Hear the comment at about the 1:14 mark of the video.)

Let's put the comment in context...

Seeing two of his singers in the bottom three frustrated Levine, but the bigger catalyst was seeing his team member, country singer Amber Carrington, as the one saved.

Some fans were outraged by the comment, voicing their anger on Twitter to which Adam responded, "joke- noun 1. something said or done to provoke laughter or cause amusement, as a witticism, a short and amusing anecdote, or prankish act."
