While Madonna may be the Material Girl, she may not be allowed to use the name for her clothing line.

The Queen of Pop - who worked on a range of clothes entitled Material Girl with her 13-year-old daughter Lourdes - is being sued by LA Triumph for using the same name as their clothing collection.

“Our client and its predecessor have been continually selling similar clothes in similar retail outlets at similar price points under the Material Girl brand since at least 1997 and Madonna and her new-found company do not have the right to trade in the same space under this brand,” lawyer Peter Afrasiabi told X17online.

Chris Arledge, an intellectual property lawyer, added, “As a result of their acts, our client faces a risk of being subsumed by Madonna’s profile, obvious worldwide notoriety and the massive spending campaign by Madonna, her company and retailers on her behalf.”
