She is known for her exacting standards when it comes to performing.
But it appears Madonna is even micro-managing her own daughter by proof-reading her blog.
The 53-year-old said that she goes through the text and sometimes edits it to make it better.
The aim was to ensure Lourdes does not become a "lazy writer," even though she is only 15.
Interviewed by Harper's Bazaar, Madonna spoke candidly about how she was bullied at school and called "Hairy Monster". She claimed that when she was younger men did not find her attractive because she was "different".
