Jessica Simpson Shows Off Weight Loss and Cleavage in See-Through Dress (PHOTOS)

Jessica Simpson knows how to do a club night the right way — a hot outfit, a hot hairdo, and a hot date!

The mom of two stepped out in Hollywood on June 8 for a night out at Warwick nightclub with her fiancé Eric Johnson. Jessica looked sexy for the evening with her hubby-to-be, showing off her figure and cleavage in a tight black dress with a completely sheer top. The singer and fashion designer paired the look with black heels and a black clutch purse. Her blond hair looked beachy and chic with long waves.

Jessica, who is a spokesperson for Weight Watchers, has been showing off her figure more and more lately. In May, the fit star posted a photo of herself working it in a bathing suit. She even reached her weight loss goal in preparation for her wedding next month. This mama looks great!
