Blue-eyed soul songstress Christina Aguilera and her record exec hubby Jordan Bratman keep the sizzle in their marriage by getting naked on Sundays.

“We claim ourselves to be coziest couple ever,” the twenty-six-year-old Grammy nominee told Ellen DeGeneres during an appearance on her talk show scheduled to air on Wednesday. “We have something called naked Sundays.”

“[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.”

Ellen has a suggestion for cooking naked Sunday dinner: “Nothing with grease – that could splatter.”

“Well, unless you want the grease,” Xtina replies.
