Jim Carrey and Jenny McCarthy have naked days.
The couple - who have been dating for around three years - reportedly enjoy stripping off when they are alone together to keep their relationship exciting.
A source said: "When they're alone they prefer to be nude most of the time. They always have an afternoon of naked fun, it spices things up. But of course they are always dressed in public!"
Jim and Jenny are said to have spent most of their recent break in Hawaii - where they splashed out $25,000 to rent a beachfront villa - completely naked.
The pair are not the only famous couple to enjoy naturism.
Christina Aguilera and her record producer husband Jordan Bratman regularly enjoy "naked Sundays".
The 'Dirrty' singer - who has a son, Max Liron, with Jordan - revealed: "We have to be the cosiest couple around. We have something called naked Sundays.
"On Sundays we just do everything in the house, and we're just cosy and laid back.
"We don't need to go anywhere, we're just with each other. We do everything naked. We cook naked. It's important to keep the marriage alive, to spice it up a little."
