"Thanks Frankie Rodriguez for making the great outfits. Dannielynn wanted to come as this," Birkhead tweeted, along with a photo of the Mary Poppins doll on which his daughter wanted to base her ladylike costume, as well as the Bert outfit she picked out for him.
Dannielynn recently became a model for the Guess Kids clothing line.
Smith was the face of Guess in 1992. She died of an accidental drug overdose in 2007 at the age of 39, shortly after her daughter was born.
Dannielynn's father is a professional photographer.
