Lourdes Leon Is Madonna's Stylish Mini-Me!

Happy 15th birthday, Lourdes Leon!

Madonna's mini-me is another year older on Friday. The budding fashionista -- who collaborated with her famous mom on the teen clothing line Material Girl -- already has an established sense of style!

Whether it's red lipstick, edgy tights or leather jackets, Lourdes is constantly emulating and putting her own twist on her mom's iconic looks.

Madonna told Us Weekly last year her daughter's style "is inspired by kids she sees in hip-hop and ballet classes, European influences, bands she listens to. You could say it's in the DNA - but I could never tell her how to dress! She also comes to my photo and video shoots, pulls outfits together and gives her input to a lot of my fashion-designer friends. Whether it's Marc Jacobs or Stella McCartney, they always ask her what she thinks."

Mom's only concern? "If anything, I wish she'd dress more conservatively," she said. "How's that for irony?"
