Jessica Simpson sure has a lot to celebrate! After spending the last few years making babies, Jess has hit her weight loss goal. That’s great news, and not just for the 33-year-old mama. We bet Weight Watchers is pretty happy too!

Jess, of course, is one of the spokespeople for the well-known weight loss company. While her relationship with them has hit a couple (baby) bumps along the road, she’s now officially accomplished the weight loss goal she’s had in mind.

First time rocking a white dress this year ...but not the last!!Thanks @weightwatchers!,” she captioned a picture of, you guessed it, herself in a sexy white dress. Her next post announced the good news about her health: “...AND a white T-shirt!!#goalreached thx@weightwatchers.”

Looking laid-back and lovely while rocking some seriously blingy earrings, Jessica’s selfie doesn’t show off much of her slimmed down look. Thank goodness for the rest of her Instagram. Just a few weeks ago she shared a pic from the set of a new Weight Watchers commercial and even sitting down, Jess looks long and lean.

Not that she’s the only star. Jessica also make sure to highlight the two little loves in her life: daughter Maxwell and son Ace. “The most beautiful girl in the world,” she writes of little Max. Like mother, like daughter, Jess.
