Christina Aguilera is Ellen DeGeneres' only guest Wednesday as the talk show host celebrates her 600th episode.

And what do the two talk about?

Getting naked.

When DeGeneres asks the pop singer to describe what a typical weekend day is like with husband Jordan Bratman, Aguilera says, "We claim ourselves to be coziest couple ever. We have something called naked Sundays."

Ellen: "Excuse me? Naked Sundays."

Christina: "You have to keep marriage alive, spice it up."

Ellen: "Because it's been how many years?"

Christina: "A big whole year. 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 and have naked Sundays. We do everything naked. We cook naked."

Ellen: "You cook naked?"

Christina: "Yeah, we cook naked."

Ellen: "Nothing with grease... that could splatter."

Christina: "Well, unless you want the grease."
