Lourdes Leon’s showbiz dreams have been dashed by her Material Mom.

A bitter battle is brewing for the mother-daughter duo after the 50-year-old pop icon turned down a small role Lourdes, 12, was offered in the upcoming dramedy The Secret Life of Bees.

“Madonna didn’t work ’till after high school, and she wants it to be the same way for Lourdes. She doesn’t want her to enter that harsh world,” a Star Magazine mole has revealed.

Nonetheless, young Lourdes has her heart on becoming a successful actress, the tabloid insider says.

“Lourdes is pretty determined, so I predict a battle in the future.”
