Canadian pop-country superstar Shania Twain is stepping back into the spotlight as a mentor on TV talent show The Voice.

She tweeted on Thursday that she'll appear on the show on April 24, to help coach young talent as they enter the final rounds of the contest.

It's a job reserved for some of music's biggest names. Previously finalists have been coached by the likes of Rihanna, Dolly Parton and Garth Brooks.

Twain is charting a return to music after suffering from dysphonia — a vocal cord disorder that she attributed to stress. She has had intensive voice therapy over the past few years to relearn how to sing.

"I'm a different singer now," she told Rolling Stone in a recent interview, adding that her voice is deeper. "There was a lot of coming to terms with that. It's been one of the obstacles in my life I've just had to learn to live with."

Twain dominated the charts in the 1990s with hits such as Forever and For Always and Man! I Feel Like a Woman.

She plans to release her first new music in 15 years later this spring, revealing she's been writing new songs that reflect in part on her painful 2008 breakup with husband and producer Robert "Mutt" Lange.

"Writing is my therapy and writing this new album helped me come to terms with a lot of things emotionally," she tweeted in March.

Twain remarried in 2011 to Frédéric Thiébaud.
