Jessica Simpson Is Glowing In Weight Watchers Shoot

Looks like Jessica Simpson is back hard to work as a celebrity spokesperson for Weight Watchers. The 33-year-old mother of two showed off her slimmed-down figure in a photo she posted on Twitter yesterday, in which she wore skinny jeans, a white button-down and cowboy boots. "Couldn't stop smiling on set for my new @weightwatchers campaign today! #happy," Simpson wrote.

In 2012, the "Fashion Star" judge inked a lucrative deal with the popular weight management brand while still pregnant with her first child for a reported $4 million. Simpson then lost a reported 40 pounds before announcing a surprise pregnancy just seven months later -- and abruptly ending her stint with Weight Watchers.

In August, Weight Watchers welcomed Simpson back as a brand spokesperson, releasing a statement that said: "We were thrilled to welcome Jessica back on the Weight Watchers program in August. With a toddler on the run and an infant to look after, we know she needs a plan that’s simple and fits into her life along with the support that’s so important to moms with young children."
