Excited to show off the fruits of her labor, Jessica Simpson posted a sexy behind-the-scenes pic of her new Weight Watchers commercial on Friday (February 7).

In the black and white shot, the former reality star has her hands on her hips in a form-fitting black dress.

Stoked for the shot, the mother-of-two captioned the pic, "Too proud to sit down!! Behind the scenes of my new commercial. Thanks @weightwatchers."

Speaking of her adorable little ones, Jessica posted a heartwarming photo of Maxwell and Ace all wrapped up in towels while sitting on daddy Eric Johnson's lap with the caption, "Bath time buds."
