LOS ANGELES — When the cameras shut off on Sunday's "American Idol" finale following 21-year-old Abi Carter's win, it marked the end of the Lionel Richie, Katy Perry and Luke Bryan judging trio that's been gracing screens across the country since 2018.

Perry had announced back in February that she would be bowing out at the end of Season 22 to "go and see the world and maybe bring new music."

Speaking with media outlets, including USA TODAY, following the finale taping, Richie admitted, "This is bittersweet because we're going to lose one of the originators, if you will."

He continued, "We were a trainwreck when we first met. I knew Katy, I knew Luke, but we had never worked together. … Once we realized that Katy's going to come out of her clothes somewhere during the course of the show – a malfunction is going to happen – and Luke is going to eat the pizza and drop it on his lap, it's enough to keep you on pins. But it worked.

"I'm going to miss this group. Katy is going to be missed."

Who's taking Katy Perry's place on 'American Idol'? Judges hint replacement possibilities

Less than an hour after filming on Perry's final "Idol" episode wrapped apparently wasn't too soon for inquiring minds to ask about what would be happening with the void she's leaving behind.

The "Idol" judges have thrown out names of Perry's possible replacements throughout the season, including Meghan Trainor and Jelly Roll, but the truth is – as far as the fans are concerned – no one has been chosen for the job yet.

But the ABC veterans have an idea of what characteristics their new colleague should have.

Richie said, "You've got to bring your character. Be who you are. Katy's Katy. It's like singing a Whitney Houston song. Don't try to sing it like Whitney; interpret it."

The next judge has to have "personality," a "quirk" and the ability to "tolerate two crazy brothers like me and Luke," he said.

Richie added, "There's a lot of artists out there that can sing, but to join a very successful team you've gotta be confident of your space. You know who you are and you'll last forever here. … It's got to be somebody that identifies with the young culture."

Perry didn't shy away from talking about the person who'll be taking her job.

"I'm leaving before I can get fired!" she joked.

On a more serious note, she added, "The qualities I hope for are someone that is honest. Someone that is constructive with their words. Someone that is leading with their heart – heart-centered and less ego – and isn't afraid to speak their mind and isn't afraid if sometimes that's polarizing, isn't afraid of negative comments, isn't afraid of getting booed just as long as they are speaking their mind and true to themselves.”

Bryan said, "It'll really be interesting to see who they choose."

Katy Perry 'What Makes a Woman' duet highlights her showstopper finale dress: 'The biggest skirt ever'

As Perry gave her final performance as an "Idol" judge – a duet of "What Makes A Woman" with third-place finisher Jack Blocker, whom she'd been skeptical of at the start of the season – her dress unfurled into a sentimental piece of art while she was elevated at least a dozen feet above the stage.

Below a metallic bodice was a skirt featuring the faces of Top 24 contestants from her seven-season "Idol" career.

"It was just going to be a pretty skirt with a silver top and I was like, 'No, let's do something. Let's make a moment. Let's pay homage to all the contestants,'" Perry said. "It was just to show how much these kids have really lifted me up."

She came up with the concept and her costume designer Heather (presumably Heather Picchiottino) made it a reality within a week, she said.

"It was just one of those spur-of-the-moment ideas, and we were like, 'Can we do this? Can we execute this in time?'" Perry said. "I was like, 'No, I want the, like, biggest skirt ever and I want to keep rising.'"

Reflecting on how she felt about closing the "American Idol" chapter of her life, Perry was enthusiastic about the winner viewers chose for her send-off.

"I'm so happy that Abi won. It was like the cherry on top for my seasons; ending there, it just felt like we've landed exactly where we worked so long to get (to)," Perry said. "She checks so many boxes.

"I think ('Idol') actually is still, now, one of the only shows that makes stars or opens doors on that path to stardom," she added.
