“I think Madonna can’t stand that Lourdes is growing into a beautiful teen,” a source blabs in this week’s edition of OK! “She seems envious of her youth and looks. She knows Lourdes is going to be gorgeous and will get the attention of the opposite sex. Knowing Madonna’s taste for younger guys, it’s a matter of course that they’ll be dating men the same age. It’s disturbing.”

According to the tabloid report, the pop icon is so determined to keep Lourdes from growing up, she’s been preventing the girl from adopting basic grooming habits. Last year, the style team for Madge’s “Sticky & Sweet Tour” were ordered not to shape Lourdes’ trademark unibrow.

Madonna reportedly refused to let Lourdes have a hairdresser at the Gucci gala benefiting UNICEF and Malawi last February.
