Fergie has gone topless to pose just in a pair of Calvin Kleins underwear in a new racy video.

The Black Eyed Peas star took to Instagram to post the clip, which was shot in black and white and she is seen posing on her bed with her arms crossed, the Mirror reported.

The clip cuts to some close-ups of her toned stomach, shots of the Calvin Klein strip on her pants, and a view of her sexy derriere with some raunchy music.
