An RCA representative was not immediately available for comment, Billboard added.
Assuming RCA has indeed parted ways with Aiken, his departure would mean that seventh-season Idol runner-up David Archuleta is now the only Idol runner-up that is still with the label they signed with after competing on the Fox reality competition.
Archuleta signed a recording contract with 19 Recordings/Jive Records last June.
