The 48-year-old singer will be joining judge Jennifer Hudson on the current series of the NBC talent competition, where she will give advice and assistance to the hopeful singers ahead of the show's Knockout Rounds.

Speaking about working with the fresh new talent, Mariah said: "The sessions with the contestants, some of them have completely blown me away. It's like a humbling experience to be around all the raw talent."

The 'We Belong Together' hitmaker admitted that she can sometimes get "caught up" in her "own world" as a singer, and said working with up and coming talent gave her the chance to step back and appreciate what other artists are "bringing to the table".

During an appearance on the 'Today' show, she said: "I'm not saying that you get jaded being in the industry or doing your own music and really being caught up in your own world, but maybe a little bit. And it's nice to see other people and what they're doing and what they're working with and what they're bringing to the table in terms of their contributions as artists. So I really enjoyed it."

Mariah's decision to join 'The Voice' may come as a surprise to some fans, as after working as a judge on 'American Idol' five years ago, the singer said she had the "worst experience of [her] life".

The 'When You Believe' singer feuded with fellow judge Nicki Minaj whilst on the show, and later said their rivalry was mostly the fault of the producers.

Asked in 2015 if she'd ever return to 'American Idol', Mariah said: "Hell no. Absolutely not. That was the worst experience of my life.

"I don't think they had any intention for us to have a good experience doing that show. Pitting two females against each other wasn't cool. It should have been about the contestants instead of about some non-existant feud that turned into even more ridiculousness.

"I would never want to be involved with it again."

'The Voice' airs Monday and Tuesday nights on NBC, and Mariah will appear on next week's episodes.
