Tensions are reportedly growing between the Black Eyed Peas, with rapper Will.i.am frustrated at singer Fergie's "arrogance".
Will.i.am has blasted Fergie for being "arrogant".
The Black Eyed Peas rapper was furious with his bandmate after a recent show in California, and is worried there is no future for the band unless she changes her ways.
A source told National Enquirer magazine: "Will.i.am was ranting after their set about how arrogant she was acting. He griped that the whole thing had become 'The Fergie Show'. He was so upset he said things are going to have to change if he group is going to stay together."
It is not the first time there have been claims of problems in the band.
Last year, it was claimed Will.i.am was upset with Fergie's decision to pursue a movie career while they were trying to make new album 'The E.N.D.'
A source said at the time: "Fergie won't commit to a tour schedule to promote the album. Making her movie 'Nine' is her priority now."
