Reports that Guy Ritchie's step-daughter, Lourdes Maria Ciccone Leon, is set to have a cameo in the upcoming "Harry Potter and the Half-Blood Prince" as a student at Hogwarts are untrue, insisted Ritchie to MTV News.

The rumor recently emerged not long after Ralph Fiennes's nine-year-old newphew Hero Fiennes Tiffin was cast to play a young Voldemort.

Meanwhile star Daniel Radcliffe says that after the increasingly dark tone of the last few sequels, 'Prince' "should be the funniest of the films so far."

Director David Yates agrees with the viewpoint saying that it's the "sex, drugs, and rock and roll" of the Potter books with massive making-out sessions to occur for several characters.
