Lady Gaga will face $5 million lawsuit filed by a Michigan Law firm, which accuses her of scamming a Japan tsunami relief charity. Plaintiff 1-800-LAW-FIRM alleges that the pop diva pocketed undisclosed amounts of cash from the sale of We Pray for Japan wristband promoted through her online store. The pop star charges $5 for the wristband, another $3.99 for shipping and handling, and $0.60 for tax. According to the lawsuit, Lady Gaga unlawfully inflated the costs involved in shipping and stole the extra.

Gaga's official site selling charity wristbands asks people to show their support for Japan tsunami victims with We Pray for Japan wristband. The site allows people to contribute an additional amount along with the actual price of $5, ranging from $5 to $100, for each wristband. The site also declares that all proceeds (from the sale of We Pray for Japan wristbands) go directly to Japan relief efforts.

I'm suing Lady Gaga simply to hold her accountable for giving the money that she was raising for charity to the cause that she was trying to raise it for, said Ari Kresch, an attorney for the law firm.

Firm partner Alyson Oliver alleged that Gaga refused to disclose the amount of cash that goes to the Japanese tsunami victims' relief.

When we tried to communicate with the defendants in this lawsuit, all we got was, 'well, some of the money is being retained, but we don't really know how much', Oliver told FOX news station.

The wristbands are still up for sale at Gaga's official store.
