Christina Aguilera likes to walk around naked, a lot.

Christina Aguilera has no problem showing skin -- especially on weekends with her husband, music executive Jordan Bratman. "We claim ourselves to be the coziest couple ever. We have something called 'naked Sundays,"' the 26-year-old pop star told Ellen DeGeneres in an interview set to air Wednesday on "The Ellen DeGeneres Show."

"You have to keep marriage alive, spice it up," said Aguilera, who married Bratman in November 2005. So the couple stays in on Sundays, she says. "We do everything naked. We cook naked."

"You cook naked?" asks DeGeneres.

Aguilera replies: "Yeah, we cook naked."

"Nothing with grease -- that could splatter," said DeGeneres.

"Well, unless you want the grease," Aguilera replies. Article here.
