Christina Aguilera, Nude, Every Sunday

No, this isn't the tagline for her latest tour.

Instead, it's what lucky husband Jordan Bratman gets to see at least once a week: Christina Aguilera nude. All day. In every activity.

"We claim ourselves to be coziest couple ever," the 26-year-old Grammy nominee tells Ellen DeGeneres on her talk show Wednesday. "We have something called naked Sundays."

"Excuse me?" DeGeneres asks, perhaps wishing to steal the idea for herself and Portia de Rossi. "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."

Sounds like this gal is nude more often tha Kim Kardashian on screen with Ray J.

Keenly DeGeneres suggests there is one thing any couple should avoid during its nude time: "Nothing with grease â€" that could splatter."

But Aguilera isn't deterred, saying: "Well, unless you want the grease."

Touche, Xtina. Sounds like you could give Daniel Radcliffe even more to ogle over.
