VIDEO - Christina Aguilera, Green Day's Billie Joe Armstrong Talk 'The Voice'

Extra recently got a few words in edgewise with "The Voice" coach Christina Aguilera and the show's newest minted mentor, Green Day lead singer Billie Joe Armstrong.

Of course, the chat led off with Aguilera offering her take on Mariah Carey recently signing up to co-judge the upcoming twelfth season of Fox competitor "American Idol." Regarded as the first major U.S. pop star to judge a primetime singing competition, Aguilera sees nothing but goodness coming from adding a legendary diva such as Carey to the mix.

"I just found out about it last night, the news is fresh," Aguilera said. "I love that all these artists are coming together from all the experience that we've had, and being able to take that and feed this new wave of talent coming up."

Likewise, she had kind praise for her "Mickey Mouse Club" contemporary Britney Spears taking up a similar gig with that other Fox competition, Simon Cowell's "The X Factor." Through the years, Aguilera comes across as still respectful and acknowledging that if anybody could teach contestants everything about captivating an audience that runs beyond octaves and scales, it's Spears.

"Britney's so talented. I mean, she's a pro. She's been at it for a number of years now," Aguilera added. As exciting as she finds being joined by Carey and Spears, she's just as (maybe more) enthused to have Armstrong stirring things up from a different angle.

"This one was very intriguing because he comes from a completely different genre of music than I do," she said. "He's had tremendous obvious stage experience and touring and he would have some amazing advice and input."

Armstrong himself said that when approached for the show, he was given his choice of coaches with whom to align himself. He joins a list of various teams' mentors that already includes Mary J. Blige and Michael Bublé that will guide contestants alongside coaches Aguilera, Blake Shelton, Cee Lo Green and Adam Levine.

"I like singers, not drummers," Armstrong joked, perhaps a nice little shot at Maroon 5 face Levine.
