Pop beauty Fergie has become the latest celebrity to admit to a lesbian romp.

The Black Eye Peas singer follows Lindsay Lohan, Lady Gaga, and Megan Fox in revealing that she is bisexual.

Fergie, who married Josh Duhamel in January, told The Sun: “Put it this way, I’ve experimented definitely, but I have never had a steady girlfriend.”

The Black Eyed Peas shot to No. 1 in the UK charts yesterday with "Boom Boom Pow" — but it is their next single that is closest to the star’s heart.

The 34-year-old star explained: “You’ll like our next video, for "I Got a Feeling," because I have a little girl-on-girl tease section of the video.

“I met the girls right before we did the scene.

“They were beautiful. They were hot.

“One of them was the director’s girlfriend — so he was happy!"
