"We claim ourselves to be coziest couple ever," the 26-year-old Grammy nominee (for her Back to Basics album) tells Ellen DeGeneres on her talk show Wednesday. "We have something called naked Sundays."
"Excuse me?" DeGeneres asks. "Did you say naked Sundays?"
"You have to keep marriage alive, spice it up," says Aguilera, admitting that some added heat is required even though the two have only been married for "a big whole year."
"[In November] we just celebrated our first anniversary, and on Sundays we just do everything in the house, and we're just cozy and laid back," she says. "We don't need to go anywhere, we're just with each other." We do everything naked. We cook naked."
DeGeneres suggests there is one thing they should avoid during their nude time: "Nothing with grease – that could splatter."
But Aguilera isn't deterred, saying: "Well, unless you want the grease."
