It was all the giddy domestic bliss one block could handle: In front of Melissa Joan Hart and Mark Wilkerson's L.A. home, the fence was festooned with blue balloons heralding the Jan. 11 arrival of their first child, Mason Walter Wilkerson. Up the street, "Pink had just gotten married [to motocross star Carey Hart] and she had white balloons on her fence," says Hart. "The funny thing is, now she's Mrs. Hart and I'm not!"

Yep, the former star of Sabrina, The Teenage Witch, 29, is officially Mrs. Wilkerson (as of 2003) and the scene inside the family's Spanish-style home is just as cheery as it is from the street. On the walls of Mason's pale-green nursery are fanciful murals painted by Hart's stepmom, Lisa Hart. In the closet is a blanket knitted by pal Kellie Martin and "we even have a little lobster sweater with his name on it," coos Mason's mom. Dad, 28, lead singer and guitarist with the hard rock trio Course of Nature, helped out with an original lullaby. Hart's review? "It's gorgeous."

To regain her prebaby body and combat a taste for sweets, Hart plans to hit Studio City's Cardio Barre for a mix of yoga, Pilates and dance, followed by the military-style drills at celeb-heavy Barry's Bootcamp. Wait, the new mom on maneuvers? "I hope to get in better shape than ever," she says. Spoken like a true maternal multitasker.
