Like a knight in shining armor, Luke Bryan came to the defense of fellow "American Idol" judge Katy Perry when asked if fans have been too harsh in their criticism of her. "Katy Perry's been dealing with stuff like that her whole career," Bryan explained during an interview at Country Music Association (CMA) Fest. "We all get it.… I mean we're judging kids that people at home fall in love with.… We're not gonna bat 1,000 as judges." "I think we get set up," he continued.
