Jessica Simpson is one proud mommy!

The 33-year-old fashion mogul showed off her supercute son Ace Knute Johnson and precious mini-me daughter Maxwell Drew Johnson on Instagram Friday, and it's very clear her and fiancé Eric Johnson's little ones got their parents' good genes!

The picture of Maxwell, who turns 2 in May, shows the blond-haired, blue-eyed beauty gazing at something in the distance. Most little girls are cute, but Maxwell's blond curls and pouty lips really do set her apart. As mama Jess puts it, this little lady is "The most beautiful girl in the world."

Ace, 8 months, enjoys a cuddle with his mommy in the next pic. Jess is all smiles in the shot and Ace, wearing some amazing whale pajamas, gazes away from the camera as he clutches mom's arm. Jessica couldn't help but gush over her and Eric's little man, too, calling him, "The most handsome boy in the world."

But Jess hasn't just been taking snaps of her kiddies and running a multimillion dollar empire--she's been working hard to get that pre-baby body back! The Weight Watchers spokeswoman is ready for warmer weather, too, when she can show off a little more of her toned and sexy curves.

She Instagrammed a pic of her svelte self in a spring dress, writing, "First time rocking a white dress this year...but not the last!! Thanks @weightwatchers!"

Jess also shared a shot of herself in a paper-thin white T-shirt, hash tagging #goalreached, adding, "thx @weightwatchers."
