Twenty years after her mother first appeared in luxury brand Guess? Inc.'s campaigns, Dannielynn Birkhead has a starring role for the same company. The daughter of the late Anna Nicole Smith, Birkhead can be seen in the spring ads for Guess Kids starting in January, when they'll appear in magazines, billboards and busses. "I think this is kind of Dannielynn's way of paying tribute to her mom in her own special way," the 6-year-old's father, Larry Birkhead, told Good Morning America.
