Her style has become synonymous with sleek and edgy ensembles.

And Katy Perry exhibited her eye for style once again as she slipped into a plunging puff sleeved corset blouse and matching skirt for Sunday night’s episode of American Idol.

The singer, 37, looked sensational in the lavender floral print two-piece which brought attention to her tiny waist and lithe physique.

It comes as Katy was blown away by 17-year-old Kenedi Anderson’s audition on Sunday’s episode of the hit show and the teenager was awarded with a Platinum ticket.

After singing Applause by Lady Gaga while she played the piano, Katy just held out a piece of paper and asked her to sign it.

‘I’m feeling threatened,’ the 37-year-old pop superstar joked. ‘They’re younger. They’re skinnier. They’re prettier! They sing really good.’

‘I need two backstage passes,’ said judge Lionel Richie, 72.

‘My head is spinning,’ said Luke Bryan, 45.

Kenedi, from Crozet, Virginia, couldn’t believe what the judges were telling her.

Katy said she didn’t understand how she hadn’t been recruited by someone. Lionel told her they were looking for the next big thing and that she had ‘answered our prayers.’

‘I believe you might be the biggest star we’ve ever seen,’ Luke said. ‘No doubt. I believe top 10.’

‘She was born to be a star,’ said Katy.

‘You were,’ said Luke. ‘You were. I truly believe that your musical journey for the rest of your life just started right here.’

‘Chills,’ said Katy.

Kenedi got her mom and Katy told her, ‘You are so good that you deserve a break.’

Luke told her that this year they were handing out special 20th year tickets during regional auditions. He told her they were giving her the 20th year anniversary Platinum ticket out of the Nashville auditions because she was a superstar and it would allow her to skip a round during Hollywood week to watch and strategize.

‘I’d like to be your manager, producer,’ said Katy.

Kenedi was overcome with joy and came out and showed her ticket to everyone.

‘The fact that I got a Platinum ticket is just so unbelievable to me,’ said Kenedi. Her family back home jumped up and down when they learned the news.

Kenedi wasn’t the only stunning performer on the two-hour Nashville audition show.

Miss America 2016, Betty Maxwell, 27, from Warner Robins, Georgia, kicked off the auditions and showed up for her tryout holding her crown. Before she came out she showed off her sash, which she said was dirty from spray tanning. Betty also said that her biggest dream would be to be the voice of a Disney princess.

Betty handed the judges her crown but said that the Miss America pageant rules stated that they couldn’t put it on. Katy desperately wanted to try it on.

‘But the real question is will you be Miss American Idol,’ Katy said.

Betty sang A Moment Like This by Kelly Clarkson. Luke clapped when she was done and Katy said she also wanted to hear her sing a little country.
