Here's an interesting exclusive rumour reported by our friend Victoria Newton at The Sun:

HOGWARTS school is set for the arrival of a very famous celebrity muggle.

MADONNA’s daughter LOURDES - nicknamed Lola - has been asked to join Harry Potter and his pals battling Lord Voldemort in the next film in the blockbuster series.

Warner Brothers approached the 11-year-old - whose dad is fitness trainer Carlos Leon - through Madge.

And I hear she’s desperate to accept the magical role.

A source said: “Lola has definitely inherited her mother’s hunger for fame.

“After all her recent public appearances, looking more like a sophisticated teen than a child, the attention on her is really growing. Offers have poured in - film offers, sponsorship.

“An executive at Warners wanted to cast Lola in the last Potter film and has renewed his interest for the next movie. Lola would love to do it - she is a huge fan.”

RALPH FIENNES’ nine-year-old nephew HERO FIENNES TIFFIN has already signed to play the child version of his uncle’s evil Lord Voldemort character in the sixth instalment, The Half-Blood Prince.

Lourdes was only offered a small part, but it could be her big break.

Musical

I can reveal she has also been approached to star in a kids’ musical similar to Bugsy Malone in development by Warner Bros.

And H&M wanted to launch a line of kids’ clothes designed by her. There’s just one stumbling block - her mum thinks she’s too young for the fame game.

The source said: “Madonna is having serious doubts over letting her do the musical.

“Even something as innocent as a clothing range she turned down on behalf of Lola.

“She wants her to lead as normal a childhood as possible.

“But she knows it’s inevitable that sooner or later Lola will become famous on her own.

“Lola has a VERY strong sense of herself. She has often said she wants to become a dancer.”

It sounds like it won’t be long before Lola starts telling her Mama, Don’t Preach.
