During her appearance on the show, the 31-year-old former 'American Idol' contestant will also bring a sneak peek of the second season of musical drama series 'Smash', reported Ace Showbiz.
The "Dreamgirls" star had a role in the first installment of the musical series. In the second season of the show, she will portray Veronica Moore, a Tony Award-winning Broadway star who impacts the lives of Karen (Katharine McPhee) and Ivy (Megan Hilty).
"Her character will represent someone who reached their Broadway dream but also paid a price for it," Robert Greenblatt, NBC Entertainment chairman, said.
This isn't the first time 'The Voice' will see an 'Idol' alumnus.
In its last season's battle rounds, the show saw Kelly Clarkson, winner of the first season of "American Idol".
