A Michigan legal group sued Lady Gaga on Friday, claiming that not all the proceeds from the sale of her Japanese earthquake relief wristbands went to the victims, according to Reuters. 1800LAWFIRM filed the federal class-action lawsuit, which also claims that Lady Gaga and her partners overcharged on shipping costs. Gaga is reported to have raised about $3 million for Japan disaster relief through the sales of the wristbands and other efforts. “Our intention via this lawsuit is to uncover any improprieties committed by Lady Gaga and appropriate the full donations assumed to the victims in Japan,” Alyson Oliver, an attorney for 1800LAWFIRM told Reuters. Lady Gaga’s spokesperson did not immediately respond to a request for comment.
