Jessica Simpson is looking GOOD!!

The mom-of-two recently showed off her fab fighting efforts in a new Weight Watchers ad—and Popdust has the photos.

Jessica flaunts the results of her hard work in a red and green patterned short dress and denim shirt paired with cowboy boots… and she looks great.

The 33-year-old credits Weight Watchers with helping her drop her pregnancy weight after giving birth to daughter Maxwell, 20 months, and son Ace, seven months.

Simpson says Weight Watchers is the perfect diet plan for her as it allows her to set small goals for herself to reach.

“It just kept me going and I was just so impressed with myself. I’m like ‘Oh my gosh, I can do this!’” Jessica explained recently.

“When I was pregnant with Ace, my second, I had already been on Weight Watchers and I had already lost over 50lbs and so I wasn’t as relaxed in my eating and everything that I was with Maxwell. But I was just already in a healthier regiment so I kept walking and staying active and Maxwell started walking.

“It’s a lifestyle and I’ve tried so many different diets and you can only stick to something for so long.”

In the new ad, Jess says her upcoming wedding to fiancé Eric Johnson has also acted as a big weight loss motivator.

“Knowing that I have the wedding coming up is an incentive to stay on Weight Watchers, count my points and stay in the gym,” she says. “I mean, when you see my dress, you’ll know.”
