Material Girl, the collection designed by Madonna and her 13-year-old daughter Lourdes, is launching next Tuesday with a party at Macy's Herald Square in New York. The line's face and muse, actress/musician/model Taylor Momsen, was hand-picked by Madonna to appear in the brand's advertising campaigns and will be performing live with her band, The Pretty Reckless, during the Macy's event. We have early behind-the-scenes shots of Taylor, Madonna, and Lourdes on set shooting the Material Girl ad images, and it's clear the mother/daughter design team are taking their fashion roles seriously, especially mom Madonna who styled Momsen on set and even took a few photos herself—while sporting her other recent design collaboration, a pair of Dolce & Gabbana collection MDG sunglasses.
