September 2 [10:00 EDT] -- Seal's relationship with longtime producer Trevor Horn has come unglued. Horn, at the controls for the singer's first two albums, was in the process of recording a third CD with the singer when process suddenly ground to a halt early in August.

Seal's label, Warner Bros., would not comment on Internet reports that the two came to blows in the studio but confirmed that Horn was off the project.

The studio, The Amoury in Vancouver, Canada, also declined to comment but said the singer was scheduled to return to the facility in mid-September with a new producer, as yet unnamed.
