Cee Lo Green says all four coaches -- including himself, Christina Aguilera, Adam Levine and Blake Shelton -- will return for Season Two of NBC's hit singing competition 'The Voice.'

"We've already been secured for a second season, so prepare to see a lot more of myself, Christina, Blake and Adam, and a host of great artists doing their thing," Cee Lo tells Billboard.com. "[All of us returning] would be the safe assumption. I haven't heard anything other than that. I'll be there, that's for sure."

NBC recently confirmed the program's renewal when the network announced its primetime lineup for the 2011-2012 season. 'The Voice' will return next year as a mid-season show on Mondays from 8-10PM ET.

Meanwhile, Cee Lo responds to 'American Idol' judge Randy Jackson's criticism that 'The Voice' coaches' chair-spinning during the blind auditions was 'gimmicky.' "Randy is a personal friend of mine, and he is well within his rights to voice his opinion," remarks Cee Lo. "I believe that's a little harsh to say that that's 'gimmicky.' I don't believe that to be true ... I believe that it was very savvy of the creators of 'The Voice' to give it a different spin. And that spin gives us an opportunity to co-exist [with 'Idol']. I don't believe we're competing; I believe there is a co-existence."

In other news, an unreleased collaboration between Cee Lo and Aguilera recently leaked online. The song, 'Nasty,' had been intended for the 'Burlesque' soundtrack, but wasn't completed in time. Cee Lo says there's a chance the two may perform it on a future episode of 'The Voice.'
