Fergie is bringing sexy back! Or at least she’s trying to.

On Friday (Feb 21), the “Black Eyed Peas” singer posted a seductive black and white video, in which she is topless and wearing Calvin Klein undies.

According to Just Jared, Calvin Klein recently launched a social media movement that encourages people to post semi-nude selfies in their CK underwear. Select photos tagged “#mycalvins” on Instagram and Twitter will be added to an official online gallery for all to see.

Supermodel Miranda Kerr and R&B crooner Trey Songz are among the celebrities who have also taken part in Calvin Klein’s social media campaign, and you can check out their photos below:
