Here we go again: Jessica Simpson's bump is poppin'! On Friday, March 15, the second-time mom-to-be dropped by Bel Bambini baby boutique in Beverly Hills, leaving with a bag full of goodies presumably for her future son, due later this year. (Fellow pregnant star Kim Kardashian dropped by the same store earlier in the week with sisters Kourtney and Khloe.)

Wearing what appears to be workout gear, the 32-year-old singer and Fashion Star mentor's baby bump, stretching out a pink stretch t-shirt, looks more pronounced than ever. (Simpson let it slip recently on Jimmy Kimmel Live that her second child is indeed going to be a boy, as Us Weekly previously revealed.) According to witnesses, Simpson registered at Bel Bambini for her son-to-be, and checked out boy-friendly designers (Splendid, Jean Bourget and Little Marc Jacobs). "She seemed to know exactly what she wanted," an observer says.

The next day, Simpson resurfaced in L.A. for lunch at Don Cuco with many blonde re-enforcements: Her adorable 10-month-old daughter Maxwell, her sister Ashlee Simpson and similarly tow-headed nephew Bronx, 4. After lunch, the happy foursome headed for some retail therapy . . . at Toys R Us.

As she awaits the arrival of her son, Jessica is happy to dote on Maxwell. This week's season-two premiere of Fashion Star featured plenty of backstage footage in which the Dukes of Hazzard star shows off her blue-eyed, blonde princess (in footage taped last year) to cast and crew.

"Isn't she cute?" she asks, while holding Maxwell and parading her around backstage. "She's my little munchkin."
