Madonna's daughter Lourdes has been approached to play a part in the next Harry Potter movie, according to reports.

The 11-year-old, who is said to be a big fan of the boy wizard franchise, was asked to appear in Harry Potter and the Half-Blood Prince, but Madonna has refused so that Lourdes can have a normal childhood.

A source said: "Attention on her is really growing. Offers have poured in - film offers and sponsorship."

If Lourdes had agreed to the film she would have worked alongside another youngster who has a famous family, as Ralph Fiennes' 9-year-old nephew Hero Fiennes Tiffin has been signed up to play Lord Voldemort as a child in the movie.
