It's a jolly holiday with Dannielynn! The 6-year-old daughter of the late Anna Nicole Smith got all dressed up to attend the Kentucky Derby with dad Larry Birkhead in Louisville, Ky. on Saturday, May 4.

The father-daughter duo dressed up like Mary Poppins and Bert from the "Jolly Holiday" scene in the 1964 Disney musical classic Mary Poppins. Dannielynn, who made her modeling debut for GUESS kids in November 2012, posed on the red carpet in a white and red dress with a matching hat and umbrella. Birkhead, 40, channeled Bert in a red, orange and yellow striped jacket, white pants, a blue bow tie and matching hat.

"Dannielynn (aka 'Mary Poppins') with me (aka 'Bert'). Due to the no umbrella policy at the racetrack we won't be flying away," Birkhead tweeted. "Thanks Frankie Rodriguez for making the great outfits. Dannielynn wanted to come as this," the Kentucky native added with a picture of Mary Poppins and Bert dolls.

Though Birkhead said he didn't do any betting on the race, he did walk away a winner. "Great day at the KY derby yesterday with the little one," he tweeted. "Only bet was on a good time."
