"Very," Adam responds when he's asked how comfortable he feels in his own skin. "Sometimes too comfortable. I can stand to be a little less comfortable. But I guess I have the right job for that ... I don't know, I don't mind it. It's fun."

And just how comfortable is he with his own body?

Apparently, comfortable enough to walk around his house naked in front of friends.

"My buddy Sean always yells at me, because I'll be having an interview at the house or something and I'll -- and it's not conscious -- I'll be kind of naked almost and it's not very kosher," he says.

And what about his and Christina Aguilera's constant onstage bickering on The Voice, and the fact that she embarrassed him recently by "calling him out" on a hypocritical tweet?

According to Adam, it's all in good fun.

"She's funny, I love that. She called me out, that's her job, you know -- to call me out on my nonsense," he says. "But I say a lot of things, you know? Some things I stand by, and some things I put my foot in my mouth a little bit, but I don't say anything too bad to where I can't recover from it. [Saying I don't like] celebrity fragrances certainly isn't the worst thing in the world."
