Bride-to-be Jessica Simpson continues to shed pounds --thanks to Weight Watchers -- and is flaunting her "sexy" & ethereal look in new fragrance ad.

The 33-year-old pop star showcases her ample cleavage and signature sexy pout in the print ad for her latest self-titled, Jessica Simpson, perfume. Simpson wore a low-cut, nude gown with cascading sparkling crystals and thin, light feathers.

The mother-of-two channeled both the delicate, feminine image of what is described as her new "ethereal signature scent." "Feathers represent a spiritual evolution, truth and lightness," Simpson said.

She also tweeted the below image with caption; "Love the ad for my signature fragrance available this August! Shot by my fav Gilles Bensimon @jessicasimpsonstyle."

"Jessica Simpson Signature opens to whimsical notes of citrus, blending hints of clementine, nectarine, pomegranate and apricot. The heart of the fragrance is a romantic floral bouquet of frangipani, night blooming jasmine, orange flower and tiger lily. Warm, satisfying dry notes of white chocolate vanilla bean accord, sandalwood, tonka bean and drift wood round out the natural beauty of this harmonious signature scent," reads a statement about the new Fragrance Collection.

The ad was released on Friday (June 27), and retails from $18 to $65. Meanwhile, the singer is set to wed Eric Johnson, father of their daughter Maxwell and son Ace, during the July 4 weekend.
