Sony Music could be facing legal trouble over the digital royalties of "American Idol" alums like Kelly Clarkson and Carrie Underwood.  

"The Hollywood Reporter" says a new lawsuit has been filed against the label by 19 Recordings, the company founded by "Idol" creator Simon Fuller that represents some of the show's biggest success stories.  

The artists entered into deals with 19 Recording and Sony as a part of their participation in the singing competition.  

The lawsuit claims Sony has been robbing the artists of digital and streaming royalties as a result of the contracts, and is seeking at least $10 million in damages. 

A rep from 19 Recordings says it did not want to file the lawsuit, but is doing so to protect its artists.  Clarkson, Underwood, Chris Daughtry and Clay Aiken are among the alums named.
