Sometimes a look says way more than words.
During a montage segment of Idol hopefuls auditioning for the panel, Perry's fellow judge Luke Bryan, asked one scruffy, guitar-carrying singer, who he looks up to as a musical artist.
"I'm sorry for this Katy… Taylor Swift," the hopeful answered nervously.
"Oh, you don't have to be sorry," Perry replied.
"I love Taylor Swift," the contestant added, emphatically.
"I love her, as a songwriter, as well," Perry stuttered, before shrugging indifferently.
Unfortunately, the brief exchange was part of a quick montage showing how many different contestants made awkward first impressions, so viewers didn't get to see just how influenced he was by Swift, or how Perry responded to his performance.
