Jessica Simpson showed off her slimmed down figure on a sexy Instagram photo intended for fiance Eric Johnson.

The mother of two crouched in the car with her former NFL player fiance, her short black and white floral dress showing off her long legs. The 33-year-old singer-turned-fahion designer also pouted, model-like in the magazine spread-looking photo with her hand in her curly hair.

"Hiding from the paparazzi, so why not pose for Eric?" The "With You" singer captioned the post on Saturday.

Simpson has been slimming down with the help of Weight Watchers in preparation for her upcoming wedding this Fourth of July weekend.

A day before the racy photo was posted on Instagram, the singer also flaunted her wedding-ready body through another picture with a friend. The singer wore a form-fitting one-shoulder black ensemble with black chandelier earrings for accessories.

She also posted a photo of her in a printed one-piece bathing suit while holding on to a golf club. She captioned the picture with "Eric's diver."

The soon-to-be-wed couple recently held a joint bachelor and bachelorette party at the Warwick in Los Angeles last June 8. Bridesmaids, groomsmen, friends, and family members joined Simpson and Johnson at the co-ed party. A source told People that the couple's "group of friends is so close" that they just wanted to party together.

Simpson is currently planning her wedding with her sister, Ashlee, who is also getting married to Diana Ross' son, Evan on August 31. This is the second wedding for both sisters. Jessica married singer Nick Lachey in 2002 and divorced in 2006. She has 2 children, daughter Maxwell, 2, and son Ace, 12 months old, with her current beae, Johnson. Ashlee, on the other hand, was married and had a son with Fall Out Boy bassist Pete Wentz in 2008 and separated in 2011.
