London: She is famed for successfully juggling her multi-million empire with motherhood but a new report claims that `Queen of Pop` Madonna only spends 15 minutes with each of her four children every day.
Madonna manages her diary in 15-minute slots and her assistant marks out appointments for her children, reported Daily Mail online.
"She will have `time with Lola` or `time with David` marked into her schedule by one of her PAs. The children have appointments made to see their mother, who will help with homework, or sing, or even make food with them, but only if it has been planned in advance," said a source close to the `Material Girl` hitmaker.
The pop icon who is now busy directing her second feature film `W.E`, has non-negotiable appointments like her two-hour-long exercise regime.
She is also busy with meetings and managing her reported USD 450 million fortune.
"Madonna`s version of motherhood is conducted on her own terms," added the source.
Her two biological children Lourdes, 14, Rocco 10, and David Banda, 6 and Mercy James, 4, whom she adopted from Malawi, are also made to attend the Friday night Kabbalah meetings.
At present there are three nannies, who look after the children and play a large and important role in the children`s lives.
The nannies all speak French, as the children are being raised in a bilingual environment and do not have TVs in their rooms, added the report.
