Jessica Simpson [1] has been no stranger to the sexy swimsuit snap this Summer [2], and she kept her hot streak going when she posted a superhot photo to Instagram on Monday [3]. Wearing a sleek black one-piece and flower crown, Jessica captioned the shot, "Oh yea girl...We are proud to be in our bathing suits!! @baylormcg #hardworkpaysoff #workoutpartnersforlife." The photo is likely from her younger sister Ashlee's poolside bridal shower over the weekend. Jessica has clearly been working hard on her postbaby body since giving birth to son Ace last year and hasn't been shy about sharing the fruits of her labor. After tying the knot with Eric Johnson [4] over Fourth of July weekend, the beautiful bride posted a hot swimsuit photo on her feed [5] that was simply captioned, "Jessica Johnson." What do you think of Jessica's latest sexy poolside picture?
