Why save the sexy costumes for Halloween when Christmas is right around the corner? For Fergie, the holidays are the perfect time for a little naughty role-playing with husband Josh Duhamel.
"One day every holiday season, he comes home and there's a naughty Mrs. Claus," the singer told Ellen DeGeneres on Monday's show. "It depends how good he's being!" (Watch the interview clip below.)

So Duhamel knows to expect an R-rated Mrs. Claus every year -- but he doesn't know what she'll be wearing (or not wearing)!
"It differs every year," the Black-Eyed Peas singer said of her costume. "It's naughty and nice at the same time. Super-cute and fun."
It does sound fun. But why limit the costume opportunities to Mrs. Claus? Here are some suggestions for changing it up:
- Naughty Snowman. Cold and hot!
- Naughty Grinch. What could be more naughty than stealing Christmas?
- Naughty Dreidel. Because sexiness does not discriminate!
- Naughty Christmas Gift. Perfect for unwrapping.
- Naughty Candy Cane. Sexy, sweet and seasonal!
No matter what kind of outfit Fergie chooses, it sounds like she and Josh will have a very merry Christmas. Though we have to wonder: What does he dress up as?
