Teddy Riley, formerly of Blackstreet, is suing Lady Gaga over her 2009 song "Teeth." He claims he produced the hit for her album "The Fame Monster," and was promised 25 percent of the writing fees but saw no money at all.
Riley is especially salted, because that album was the work that made Gaga a household name. He's suing for a hefty $500,000 plus punitive damages.
