Fergie: 'I still dress up for sex'

Black Eyed Peas star Fergie has confessed that she has a "big chest" of outfits to wear in the bedroom.

The R&B star, who wed Josh Duhamel in January, insisted that marriage has not changed her sex life.

"Oh, girl, I've got a big chest of fun little numbers, ones that I would never wear in public," she told Allure.

"Nothing's changed in that department. I like to have fun with my costume on stage; why wouldn't I in the bedroom?"

The singer and actress also laughed off recent pregnancy rumours, which she claimed started when she put on 17lbs for her role as a prostitute Saraghina in new movie Nine.

"If I don't do sit-ups, my stomach sticks out," she said.
