Madonna ''lives'' in her daughter's shoes.
The 53-year-old singer loves 15-year-old Lourdes' Converse sneakers and admits the pair often exchange footwear.
She said: ''I live in her Converse sneakers. She's always wearing my combat boots. She does have amazing style.
''But I'm the typical mother, where I say, 'You can't go to school dressed like that!' ''
If Lourdes - who Madonna had with her ex-lover Carlos Leon, a personal trainer - does misbehave, the star likes to maintain a strict parenting relationship.
Madonna - who launched the Material Girl clothing line with Lourdes - added to Life & Style magazine: ''She's a rebel! I take her phone away.''
Madonna - who also raises son Rocco, 11, from her marriage to Guy Ritchie and six-year-old adopted children David and Mercy - recently revealed she was not as tough a mother as she would like to be, and she was not happy when she discovered her teenage daughter smoked.
When asked if she is strict parent, the controversial pop star - who recently released her new album 'MDNA' -replied: ''I think I am, but honestly I don't think I'm as tough as I should be. I think I need to be maybe tougher. It's hard though. Every day is a negotiation.
''Cigarette smoking I'm not very fond of, for anyone, I don't approve of anyone smoking cigarettes, most of all my daughter.''
