Lady Gaga is being sued by famed R&B singer Teddy Riley, who claims she cheated him out of his contribution for the song, "Teeth."
According to the lawsuit, Riley produced the hit song back in 2009.
He claims he was promised 25% of the writing fees but got nothing.
The song was featured on the album, "The Fame Monster" the same year and turned her into a global star.
Riley who became famous in the 90s R&B group Blackstreet feels betrayed.
He's suing for $500,000.
