This earned a chorus of boos from the audience at the Disney Aulani property in Hawaii.

Buzaladze tried to seek an exception for Perry, asking, “Liner?

Katy got booed!”

Added fellow judgeLionel Richie: “Whoa, hostility!”

Perry took the boos in stride, however, and did not relent to Buzaladze’s request for eyeliner.

“Okay, first time in six seasons,” she said of the booing.

But what I’m saying is that I’d like you to flip the script.

I think we want to be, like, pulled in by our hearts, too.

I’d love to see that, and I think America might, too."

The contestant hadanother notable moment with Perryearlier this season.

The judge hugged a visibly upset Buzaladze after she apologized for a less-than-stellar performance in the duet rounds.

“I wanted to tell my side of the story and I felt so bad I was frozen.

“I didn’t speak up because I didn’t want to cry on stage.

But after I left the stage I was just destroyed.

So I wanted to apologize for that.”

Perry also addressed her remarks to Buzaladze about needing to have “more grace.”

Apparently part of being real includes cutting back on the glitter.
