Mariah is being sued for at least $20 million in damages by Andy Stone, who says he co-wrote and recorded a song called "All I Want For Christmas Is You" a couple years before Mariah dropped her track with that same title.
According to the lawsuit, Andy claims he recorded his back in 1989 in Nashville, and says it got extensive airplay and even made it to the Billboard charts during the 1993 Christmas season, and he even filmed a music video.
Andy claims Mariah and her camp never sought or obtained permission to use that title.
