The 53-year-old queen of pop is more than happy to adopt items from Lourdes' wardrobe - "I live in her Converse sneakers," the singer told Life & Style magazine at the launch of her fragrance, Truth or Dare.
"She does have amazing style. But I'm the typical mother, where I say, 'You can't go to school dressed like that!'"
It seems that the wardrobe thievery cuts both ways, though: "She's always wearing my combat boots," added Madge.
We don't know whether to feel miffed or pleased that our own mothers never showed much interest in nicking our stuff when we were teenagers. Perhaps they just weren't that into chunky Vans and belly tops?
