Dannielynn Birkhead does Derby day

They looked like they had just stepped out of the Jolly Holiday scene from Mary Poppins.

Dannielynn Hope Marshall Birkhead, daughter of model/actress and Playboy playmate Anna Nicole Smith who died in 2007, and her dad, Larry Birkhead, have always done it up for the Kentucky Derby. And Saturday they really went all out as they posed on the red carpet at Churchill Downs on Saturday in special costumes made just for the day.

"Dannielynn wanted to come as this," tweeted dad Larry with a photo of the characters from the film.

Dannielynn, 6, who became the face of Guess kids in March, seemed like a natural as she hammed it up for cameras.
