The No Doubt singer, 48, who recently released the festive album "You Make It Feel Like Christmas", told Extra that she's already making plans for a family holiday with Shelton and her three boys with ex-husband Gavin Rossdale.
"That y'all must be running out of people", the Oklahoma-born singer told when he found out he was People Magazine's pick, "Like, Wow, we're down to somebody who is somewhat symmetrical".
"I can't wait to shove this up Adam's ass", Shelton reveals in his People cover story.
The country singer also serves as a judge on "The Voice". "I think to describe myself as a child, one word comes to mind".
"As proud as I am and honored that you guys asked me", he joked to People, "that's really the only thing I care about". "And that's fat", he said. And I'm still fat today. He hops on the treadmill to stay in shape, though he acknowledges the allure of chips and dip, a bag of Cheetos when he's starving and a trip to Sonic when he's back home in Tishomingo.
"What? Oh my god, well they got that right!" And then I'm not hungry again until 10 o'clock, well what's in there? "It is really bad", Shelton admitted.
If in fact Shelton was ever reluctant about the title, he doesn't seem so now.
"When [people] would say to Adam, 'Mr".
"The Voice" coach went on to say that if people refer to him as the "Sexiest Man Alive", he will reply, "You're damn right, I'm Mr". The 41-year-old Shelton relented, deadpanning he's been "ugly" all his life so he'll take the yearlong reign with a smile.
