Adam Levine and Blake Shelton have weighed in on their possible replacements should they choose to leave The Voice.

Levine and Shelton have been mainstays since the very first season of The Voice, along with host Carson Daly. If either Levine or Shelton were to leave their spots it would potentially be a devastating blow to the popularity of the show, so thankfully neither have any intentions of leaving just yet.

The two coaches spoke with Yahoo recently about who could possibly replace them, and they had very different answers.

"Well, I am irreplaceable," Levine quipped. "I'm an excellent coach. I almost win every year... I will tell you this much: I will never take a season off. If I take a season off, it will be for every season thereafter, in perpetuity, for the rest of my life."

Many coaches have taken seasons off before returning, including Christina Aguilera, CeeLo Green, Usher, Shakira, Gwen Stefani and now Miley Cyrus. Of course, these coaches have not won anywhere near as many seasons as Levine or Shelton, who have three and five victories, respectively. Aguilera, Usher and Pharrell Williams are the only are the coaches to have won The Voice with their artists, with one victory each.

So who does Shelton suggest for a replacement? Coach Alicia Keys suggested fellow country star Chris Stapleton but he went in a very different direction.

"I don't know about Chris. Chris is too nice. Chris is a nice, friendly, shy guy. We need somebody that's, like, going to come in swinging," he said. "So I'm gonna say David Lee Roth!"

Roth would certainly be an fun choice for The Voice, and Shelton seems to want him on the show in some capacity: "Come on! Let's get Dave in here!"

The Voice season 12 premieres Monday, Feb. 27 at 8 p.m. ET/PT on NBC, with Levine, Shelton, Keys and Stefani as coaches.
