It's every fashionista's dream – having style icon Madonna's wardrobe to dip into.
So it's no surprise that 13-year-old Lourdes sometimes borrows from her famous mum.
But the cool teen had a surprising admission for fans at the launch of her clothing line this week – the tables are often turned.
When asked if she wears items from her queen of pop mum, she responded: "Oh my god, like all the time! But she does the same thing to me now.
"But it's so annoying, because my feet skipped her shoe size, and it's so frustrating."
The physical similarities between mother and daughter were striking as they joined Gossip Girl star Taylor Momsen at the Material Girl launch at Macy's in New York.
Though with her choice of outfit – a biker jacket, ripped tights and a flannel shirt - Lourdes had gone more punk than her mum, glam in a LDB.
