The Voice has signed on Shania Twain as the key adviser for Season 12's first live show later this month.

NBC has announced Twain, a five-time Grammy Award winner and country/pop icon will mentor The Voice's talented Top 12 artists on the Monday, April 24 broadcast from 8-10PM ET/PT. 

Twain, 51, posted on Instagram that she's "excited" to appear on The Voice this season.

Twain will be the second key adviser the franchise has utilized for the uber-important live shows. Last season, country star Garth Brooks filled the role.

Following in Brooks footsteps, Twain will motivate, inspire and guide the 12 contestants along with The Voice's coaches Adam Levine, Blake Shelton, Gwen Stefani and Alicia Keys.

In a bit of a different format, key advisers before Brooks -- such as Faith Hill, Tim McGraw, Miley Cyrus and Taylor Swift -- worked with artists throughout "The Knockout Round" on The Voice.

Twain has sold more than 100 million albums and remains the top-selling female country artist of all time. Twain is the first and only female to receive CMT's Artist of a Lifetime Award, and her biggest hits include "That Don't Impress Me Much" and "Man! I Feel Like a Woman!"

The Top 12 artists will be determined via "The Live Playoffs," which will air Monday, April 17 and Tuesday, April 18 at 8PM ET/PT on NBC.

For the Playoffs, 20 hopefuls will perform solos live on TV for home viewer votes. Each night of the Playoffs will feature two whole teams taking the stage. 

America's real-time vote will send two people on each team to the live shows and then the coaches must choose the last person they'd like to see move forward in the competition, ultimately eliminating two singers. The results will be revealed on the same night as the performances.
