Jessica Simpson loves motherhood! The svelte mom of two just shared Instagram pics of her towheaded tots, daughter Maxwell, 21 months, and son Ace, 7 months.

The fashion mogul posted a pic of herself and her lil' boy, who was wearing blue whale pajamas with the caption, "The most handsome boy in the world."

In addition to the pic of precious baby boy, the proud mama shared a close-up photo of her lookalike daughter with the caption, "The most beautiful girl in the world."

Jessica has been on cloud nine recently. This week, the engaged star highlighted her stunning weight loss in her latest Weight Watchers ad.

Wearing a skintight white dress, the 33-year-old, who is the spokeswoman for the diet food company, said, "When I started Weight Watchers, I didn't know what to expect at the meetings."

Jessica continued, "It reminds me we don't have to do this alone. It's so much better to have some back up since we all face similar challenges. I can honestly say I've never been happier!"

Those words definitely seem true to us -- the perky blonde has never looked happier to us!
