American Idol: Katy Perry passes out after watching wedding singer Uché Ndubizu as top 20 perform

Katy Perry pretended to pass out on Monday’s episode of American Idol following an ecstatic performance by one of the most flamboyant singers in the top 20.

Wedding singer Uché Ndubizu, 24, only scraped through the season’s auditions, with Lionel Richie, 69, initially voting against him progressing.

But his transformation was so dramatic he brought out the wildest response to a night of performances that host Ryan Seacrest, 44, said gave him ‘chills.’

Katy – wearing a bright pink gown with a heart symbol in front – had already pointed at the goosebumps on her arms as Uché delivered his driving version of Jessie Reyez’s Figures.

When he finished, she stood and turned to fellow judge Lionel – then pretended to collapse from shock.

Luke Bryan, 42, initially pretended to fan her before taking a selfie.

‘Honestly, who the hell are you?’ Lionel finally asked Uché. ‘When I’m prepared, when I think that’s it – you go to another level. It’s crazy! I love you.’

Telling him that he had ‘all the tricks in the bag,’ Katy, 34, advised him to ‘keep finessing’ his performances, teasing him as she stressed: ‘Because you’re a lot – there’s no subtlety to Uché.’

Luke then marveled at his close-shave in the auditions, saying: ‘We almost sent him away! It’d have been a cataclysmic mistake. Incredible.’

Wade Cota, 27, appeared to bring one of the biggest surprises of the top 20’s solo performances when he sparked tears throughout the audience with his version of Kodaline’s All I Want.

‘This will sound cliché – a star is born,’ Luke stated emphatically.

Lionel, meanwhile, insisted: ‘The music business needs to be inspired. Somebody has to come and shake the world up and that voice you have I know that’s you, my friend. Congratulations.’

Dishwasher Alejandro Aranda, 24, had been a clear frontrunner right from the auditions where Luke said he was ‘in the presence of greatness.’

He further cemented that with his inspired transformation of Post Malone’s I Fall Apart which had Luke telling him: ‘I am not worthy to critique you.

‘I don’t know if this show in the history of the whole show has ever had somebody like you in my opinion.’

‘I agree with Luke – there has been nothing like you,’ Lionel added. ‘You’re very special.’

Katy smiled as she told him: ‘You’re so much cooler than I. That arrangement was so next level. It was, ”Yes! I want my boyfriend here, I want a glass of wine in my hand, and I wanna watch the show, Alejandro.”

After Alejandro walked off stage, Luke predicted: ‘He’s gonna be a ginormous artist.’
