Kelly Clarkson will be serving as the key adviser for The Voice's thirteenth-season Knockout Rounds.

NBC has announced the Grammy Award winner will mentor the 32 remaining artists during "The Knockout Round," which will begin airing Monday, October 30 at 8PM ET/PT.

As a key adviser, Clarkson will work alongside the show's coaches -- Adam Levine, Jennifer Hudson, Blake Shelton and Miley Cyrus -- to motivate, inspire and guide the artists competing in the Knockouts.

In addition to the October 30 episode, the Knockouts will continue on Monday, November 6 from 8-10PM ET/PT and Tuesday, November 7 from 8-9PM ET/PT.

Famous faces who have served as key advisers before Clarkson include pop icon Taylor Swift, Fun frontman Nate Ruess, and Coldplay's Chris Martin.

In "The Knockout Round," two members from the same team are able to sing a song of their choosing one at a time. The artists' coach must then decide which of the two singers should remain on his or her team going forward, and each coach is allowed one "Steal."

As previously announced, Clarkson is also set to join The Voice as one of the four main coaches for Season 14 in Spring 2018. She will sit next to Alicia Keys, Adam Levine and Blake Shelton in a big red chair.

NBC's announcement of Clarkson's starring role on The Voice came only a couple of days after reports surfaced in May she was ABC's top choice to sit on the judging panel for the network's American Idol revival, which is scheduled to debut next year.

The Texas-born, Nashville-based singer and songwriter first entered the spotlight when she competed on American Idol in 2002 and was crowned its first champion.

Clarkson boasts more than 25 million albums sold worldwide, and her hits include "Breakaway," "A Moment Like This," "Since U Been Gone," and "My December."

In addition, Clarkson has won 12 Billboard Music Awards, four American Music Awards, three MTV Video Music Awards, two Academy of Country Music Awards, two American Country Awards and one Country Music Association Award.

Her latest album, Meaning of Life, will be released on October 27, 2017.
