Christina Aguilera's got a great one, but it's not for the timid: naked Sundays.

That's right, Christina has revealed she keeps her marriage alive to music exec husband Jordan Bratman by stripping bare on Sundays.

She told US TV host Ellen DeGeneres: "We claim ourselves to be the cosiest couple ever. We have something called 'naked Sundays'.

"We don't need to go anywhere, we're just with each other. We do everything naked. We cook naked."

But cooking in the nude could be dangerous, Ellen commented: "Nothing with grease - that could splatter."

If only Ellen knew what went on behind Christina's closed doors...

The singer replied with a smile: "Well, unless you want the grease."

Can we say TMI?

But with a body like Christina's we too wouldn't be shy about our own sexy antics.
