Dannielynn Birkhead, the 6-year-old who lost mother Anna Nicole Smith at the age of five months, is now modeling. The Playboy pinup's daughter is making her debut with Guess — the same brand Smith modeled for early in her career, although Dannielynn's working with the kids line. "The first thing she asked is, 'When will I be on the shopping bags like Mommy?'" said father Larry Birkhead. "I know that Anna's looking at this and seeing how great this will be."
