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".
Earlier this year Madonna and Lourdes launched their own US fashion label together called Material Girl. The accompanying blog features advice and tips to young girls and looks every inch the work of a teenager, even if that isn't actually the case.
Madonna claimed that Lourdes "loves fashion and style" and that her job is to "stand in the background and watch".
But she admitted: "I proof-read her blogs and edit them and give her a hard time when I think sheÕs being a lazy writer."
In the interview, Madonna, who has three other children - Rocco, 11, along with David, six, and Mercy, five, who were both adopted from Malawi - criticised people who write her off because of her age.
