MADONNA put her daughter to work over the summer (12) as a wardrobe department assistant on her world tour.

The Vogue superstar has been performing around the globe on her MDNA trek, which has been the highest-grossing tour of 2012 after pulling in ticket sales of more than $296 million .

But the hefty profits didn't stop her from encouraging her eldest child Lourdes to get a summer job just like her friends.

In a blog for her Material Girl fashion line, the 16 year old writes, "This summer I was surprisingly productive. So, I thought I would tell you all about the joys of folding underwear. As you probably know this woman I like to call my mother went on tour for her MDNA album.

"As a summer job I decided to work in the wardrobe department. All of my friends were getting summer jobs and I wanted one too. Mine was a little unconventional but still a great experience and a lot of fun.

"Being in the wardrobe department meant me and a few other girls dressed the dancers during the show when they had quick changes.

"Thirty seconds to totally dress a sweaty dancer can be insane and provoke mucho (sic) anxiety. Doing this night after night was pretty cray (crazy), but I loved every minute of it."
