But in an interview that aired this weekend on CBS' 60 Minutes, Shelton and wife Miranda Lambert - separately - speak on their careers, their lives together and why they won't ever do an interview with each other in the same room.

"I know that would be interesting," he said of the idea of he and Lambert sitting down together for interviews. "We try so hard to keep people's focus on what we do and not our marriage. It's almost impossible to do that."

He said he doesn't want to open that door any further to give "every other magazine out there a two second quote that turns into alien babies. "When we do interviews, I love talking about her. I could talk about her all day," he added. "All we've got left is she and I and our home and we just want to keep it that way."
