Jessica Simpson is launching a new bikini line. The busty pop star/actress will reportedly debut the swimsuit next month (Jul07) during Mercedes-Benz Fashion Week in Miami Beach, Florida. A Simpson insider tells American magazine In Touch Weekly the swimwear line features skimpy designs and more modest one-piece suits. The singer, who helped design the outfits, is so invested in the new line she is personally selecting the models who will show off the stylish suits on the catwalk. The beachwear is the latest venture for enterprising Simpson, who also boasts a skincare empire, hair extension project and a shoe and clothing line.
