It was mommy and daughter day for Jessica Simpson and her baby girl, Maxwell, on Sunday.

The six-months' pregnant starlet and her adorable little one lunched in Calabasas, Calif., where Simpson, 32 clad in a long, leopard print skirt and a black, cleavage-baring top showed off her very visible baby bump.

With Maxwell in her arms, the Fashion Star mentor, who also wore dark shades, held her stomach.

Jessica's little sis, Ashlee, recently praised her older sibling, telling PEOPLE, "She's a great mom and a great pregnant lady."
