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.
