Dancing With The Stars ballroom professional Julianne Hough was an original star of the Harry Potter movies. The dancer, who has teamed up with racing driver Helio Castroneves in the current season of the reality TV contest, played "a little Gryffindor" in Harry Potter + The Sorcerer's Stone. She recalls, "I gave Daniel Radcliffe, Harry Potter, a love note and a Valentine's bear."
