She's looking great!

Jessica Simpson showed that she can bounce back from having a baby again when she posted a photo flaunting her new svelte figure via Twitter over the weekend.

"Couldn't stop smiling on set for my new @weightwatchers campaign today! #happy," she tweeted on Friday, Nov.

The 33-year-old entrepreneur has even more reason to smile as she will make her return to Weight Watchers following the birth of her son Ace.

Seems like everything's looking good for her!
