Kelly Clarkson to appear as mentor in 'The Voice' season 14 knockouts

Kelly Clarkson will be appearing on "The Voice" season 13 ahead of her season 14 coaching debut. NBC revealed Clarkson's involvement in the season 13 knockout rounds, which begin next Monday, Oct. 30, in the official episode descriptions released by the network.

Clarkson, who had previously appeared as Team Blake's battle rounds mentor in "The Voice" season 2 and as a musical guest multiple times after that, was named a coach of season 14 earlier this year. Her guest appearance next week is par for the course with NBC, which has established a pattern of having incoming coaches onto the show a season before to promote them with audiences. Miley Cyrus, whom Clarkson is replacing in season 14, also appeared on the show as a knockout rounds advisor before she started her full-time coaching gig. Other coaches, like Alicia Keys, have also shown up as musical guests ahead of their format debuts.

It's also efficient, as Clarkson is already on the Universal Studios Hollywood lot working on "The Voice." When it was announced that Keys would be returning to coach season 14 last week, it was Clarkson who introduced her, presumably either pre-taping these knockout appearances or preparing for season 14, which will start in early 2018 with the two women joining Adam Levine and Blake Shelton on the panel.

For longtime "The Voice" fans, this is neither that surprising nor particularly game-changing. It's a marketing move for NBC to build up anticipation toward Kelly Clarkson as a full time "Voice" coach, and those existing fans know what to expect from her as an advisor, given that she's already filled that purpose once. But for those who are newer to the series, hiring her as the knockout rounds advisor could be their first exposure to her in any sort of non-performing capacity, as well as a refresher for anyone who doesn't remember season 2 (which was five years ago). This is the expected move for "The Voice" and the one that makes the most business sense, too.

Clarkson will appear in the episodes airing Oct. 30, Nov. 6 and Nov. 7; "The Voice" is running a "best of the season" clip show on Oct. 31 according to TV listings. She'll then become a regular panelist starting at an as yet unknown date in early 2018.

Before that, fans can get their tickets to see Adam Levine and Maroon 5 perform live at Las Vegas's Mandalay Bay Events Center on Dec. 30 and Dec. 31. Tickets are on sale now through AXS.

"The Voice" airs Mondays and Tuesdays on NBC.
