Madonna's daughter steals clothes from her wardrobe.

The 51-year-old singer - who recently announced plans she was working on a juniors clothing line - admits 13-year-old Lourdes is a huge fan of fashion and gets inspiration from her mother's outfits.

She said: "It's weird because my closet doesn't really have that much of that look so she's somehow figured out a way to do it on her own... thrift shops and taking bits and pieces from her favourite stores... stealing stuff from my closet and she creates this look that is her own, but also influenced by the early '80s and the way that I used to dress, so I think it's in the DNA."

Lourdes is helping Madonna on her Material Girl clothing range - which will be launched in September and available at US store Macy's - and the 'Celebration' hitmaker is enjoying working with her.

She told TV show 'Access Hollywood': "When she chooses her own wardrobe for when she's going out or going to school or whatever, I have a lot of input, but when it comes to designing the line it's pretty much her point of view.

"The most fun is when Lourdes comes into the room and takes over and pulls out all of her favourite stuff and starts going through the racks and just takes over. I just sit on the conference table and watch and let her do the work - it's nice, it's refreshing."
