Jessica Simpson has debuted her official post-baby beach body via Twitter.

Jessica Simpson, 33, retweeted a picture of herself wearing a one-piece white bathing suit while gearing up to shoot ads for her Jessica Simpson Collection on Friday, November 15.

“Guess which mama I get to play dress up with today?” Jessica Simpson’s stylist Nicole Chavez wrote. Shortly after, Simpson retweeted the photo and added: “;) @JSCollection.”

In the hazy photo, Jessica Simpson shows off her svelte physique while sitting outside poolside in a cleavage-baring suit. She’s also seen arching her back while placing her right hand on top of concrete surrounding the water, with her blonde locks down and swept to the right side concealing her face.

The mother of daughter Maxwell, 19 months and son Ace, 5 months, has been working out since giving birth to her baby boy in June.

One week earlier, Jessica Simpson shared a picture of herself while working with Weight Watchers.

Weight Watchers previously helped Jessica Simpson drop 70 pounds after giving birth to Maxwell in May 2012.
