It's no secret in the music world that Taylor Swift and Katy Perry are adversaries—and their feud came to the forefront once again during Perry's American Idol judging gig.

The songstresses were once friends, but their falling out was first signaled by Swift's song "Bad Blood." Perry's clap back was through her own song, "Swish Swish," which took aim in a similar way, subtly digging at her former ally through clever lyrics.

Perry has publicly acknowledge their feud before, claiming their friendship ended due to a dispute over tour dancers. Things have been somewhat quiet between the two pop stars recently, but fans haven't forgotten about the famous feud.

In Sunday's (March 18) episode, Perry's fellow judge, Luke Bryan broached the delicate subject unknowingly when he asked a contestant, "Who do you look up to as an artist?"

The contestant then awkwardly chose to apologize to Perry for admitting to be inspired by Swift. Perry seemed flustered, though she did keep things cordial. "Oh, you don't have to be sorry at all," she told the contestant. "I love her as a songwriter as... as well."
