"As promised, here's a little tease of what's to come!" Jessica Simpson's little sister tweeted. "In this tease I do drop the F bomb, so you've been warned!"

In the 50-second teaser, the slim blonde rocks a variety of looks, including a tattered tee and lingerie, an ivory mask and a loose-fitting striped tank top.

"It's interesting because there's two sides of it -- there was a side that was a bit more folky, but lately it's been a bit more dance," Simpson (mom to Bronx, 3, with ex-husband Pete Wentz) said of her the album's sound. "It's more of an electronic feel."

Simpson is planning to unveil the full-length song and video on Nov. 21.
