Jessica Simpson is proudly flaunting her post baby body once again, this time around the mother of two showed off her slimmer figure in a new photo while working with Weight Watchers on Friday, November 8th.

According to Us Weekly, the 33-year-old previously had a total baby weight loss of 70 pounds after giving birth to daughter Maxwell, 19 months, and has continued to shed pounds since delivering son Ace in June.

The singer took to her Twitter account to share her excitement with her followers. She wrote, "Couldn't stop smiling on set for my new @weightwatchers campaign today! #happy."

Attached to the caption was a photo of the blonde wearing dark jeans, boots and a tight-fitted white button down shirt while standing in a field. The designer smiled bright as her beautiful blonde locks spilled down in waves around her shoulders.

Jessica Simpson told Tumblr's MomFeeds blog in an interview in late October, "I'm a lot more confident this time around."

She continue, "With Maxwell I didn't think about the weight I was gaining, and the first time I stepped on a scale and looked at the number...I mean, that wasn't a number I had ever even considered...and I was faced with a pretty serious truth."

In August, Simpson opened up about her weight gain during an interview with Us Weekly. She said, "I am just one of those pregnant women who gains a lot of weight."

She went on to admit, "I have really big boobs. I have my curves. Even trying as hard as I did with Ace, I still gained -- definitely not as much as with Maxwell, but still a significant amount."

She explained that "With a toddler on the run and an infant to look after I knew I needed a plan that's simple and fits into my life, along with the support that's so important to my success," adding, "I know Weight Watchers works, so I got on the plan again."
