Black Eyed Peas singer Fergie, whose husband Josh Duhamel stands accused of a steamy stripper dalliance, spoke of exploring lesbian sex before she got hitched.

Fergie said that while she experimented sexually, she did not enter a serious relationship with a woman. She said: "I’ll put it this way, I’ve experimented definitely but I have never had a steady girlfriend."

Fergie's girlish fancies are played up in the video for the song I've Got A Feeling. She is seen flirting with women at a party. She said: “I have a little girl-on-girl tease section of the video. One of them was the director’s girlfriend. I just met the girls right before we did the scene. They were beautiful though. They were hot."

Fergie also recently went on the record to talk about the strength of her marriage to Duhamel amid the simmering scandal.
