Christina Aguilera Naked Sundays, Ellen show

“We claim ourselves to be the coziest couple ever. We have something called naked Sundays. You have to keep marriage alive, spice it up. 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."

– Christina Aguilera
