Jessica Simpson
is one proud mommy!

The blonde beauty shared some new snapshots of her adorable son Ace and her mini-me daughter Maxwell on Instagram Friday. 

"The most handsome boy in the world," she wrote, along with a candid snapshot with her little man. In the photo, the 8-month-old tot is cuddling with his mama and sporting some super cool pajamas.


The picture of Maxwell, who turns 2 in May, shows the blonde-haired, blue-eyed beauty gazing at something in the distance. Maxwell clearly inherited her mama's blonde curls and pouty lips. We agree with Jessica, who calls her "the most beautiful girl in the world."

Simpson definitely loves her kiddos, but she's managed to find time to whip her post-baby body back into shape!

The mother-of-two flaunted her fit figure in a new Weight Watchers ad, showing off her hard work in a tight white dress.
