The erotic couple strip down on Sundays to keep their marriage exciting.

On the Ellen Degeneres show, Aguilera claimed they are the coziest couple ever and do everything naked on the weekend .

"We claim ourselves to be coziest couple ever. We have something called naked Sundays," said the 26-year-old Grammy nominee (for her Back to Basics album).

"Excuse me? Did you say naked Sundays?" De Generes asked. To which the pop star replied: "You have to keep marriage alive, spice it up."

"[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.

We don't need to go anywhere, we're just with each other. We do everything naked. We cook naked," the singer added.
