13-year-old wows 'The Voice' coaches with her jaw-dropping cover of Adele

Now, this is a performance!

While season 15 of 'The Voice' has only just begun, Kennedy Holmes has already stolen the show after shocking the judges with her powerful singing voice.

The 13-year-old from St. Louis belted out a jaw-dropping rendition of Adele's "Turning Tables," with all four coaches turning around before she even hit the final note.

"I think she could win," country singer Blake Shelton said right after the performance.

"I think you are the best vocalist that has auditioned this year. Your voice already sounds so seasoned and accomplished. So much control, so much range."

He even went on to call her "the greatest artist of all time" and pleaded with the teen to choose him as her coach so she could teach him to sing.

Fellow coach, Adam Levine added: "Very very rarely does somebody come around that reignites our passion. After 15 seasons, you actually could become the absolute biggest thing to ever come from this show."

But her mind-blowing performance wasn't even the best part of her audition ...

As soon as Jennifer Hudson started talking to her, Kennedy burst into tears, explaining that it's always been her dream to sing with the former 'American Idol' finalist.

"I'm ready!" Jennifer replied, before grabbing a microphone and joining the young singer on stage for one of the most incredible blind auditions this series has ever seen.

We can't wait to see her perform again!
