Kelly Clarkson’s vocals have impressed one of her biggest fans.

The slimmed-down talk show host, 41, left Katy Perry in awe after singing one of her greatest hits during a ‘Kellyoke’ segment last week.

In response to footage of the American Idol winner performing a powerful rendition of Perry’s 2012 track, Wide Awake, on Instagram, the 13-time Grammy nominee left a hilarious reaction to Clarkson’s rendition.

‘Ok dang I can never sing that again,’ the mother-of-one joked.

Fellow American Idol alum Adam Lambert expressed his awe,  ‘❤❤❤❤❤❤’.

Kelly Clarkson, 41, blew her fans away when she shared a Katy Perry song in a Kellyoke performance on The Kelly Clarkson Show last week

One fan offered a little bit of background on the performance.

‘I had the honor to be at this taping and let me tell you all, this was Kelly tired!!! Her voice blew me away,’ the audience member wrote. ‘She’s AMAZING and always gives us 110%! If you ever get the opportunity to see her show live…do it! It’s a blast! ❤’

This wasn’t the first Katy Perry song the hitmaker has been attracted to.

Clarkson included Long Shot, which was co-written by Perry, on her 2009 album All I Ever Wanted.

She has also performed other hits by the American Idol judge, including Roar in 2019 and The One That Got Away in 2023.

The show host has performed hundreds of songs since debuting The Kelly Clarkson Show in 2019, and even compiled a record of her Kellyoke recordings.

‘Over 500 songs later, and we’re still not running out of amazing artists to pay tribute to,’ she said when EP was released in 2022.

The versatile singer has covered just about every genre of music on her show.
