R&B hitmaker Teddy Riley is coming for Lady Gaga after allegations that she never paid him for his contributions on "Teeth," a record from her chart-topping album The Fame Monster.
The former member of singing groups Blackstreet and Guy claims he was promised 25% of the writing fees but got zilch since the LP's release in 2009.
Riley is suing the Mother Monster for $500,000 plus punitive damages, according to TMZ.
The Fame Monster also features such Gaga hits as "Bad Romance," "Alejandro" and "Telephone" featuring Beyoncé. The record has sold 1.56 million copies in the U.S. alone.
