'Take That' band-mates; Gary Barlow, Howard Donald and Mark Owen recently expressed that Jason Orange's departure would be a "huge loss" for the band.
The 44-year-old has announced that he would not be recording a new album with the band but there had been "no fallings out," the BBC reported.
Orange also mentioned that he had spent some of the best years of his life with them.
The original band formed in 1990, split up in 1996 and four of the five members reformed for a successful comeback in 2005. The fifth founder member, Robbie Williams, rejoined briefly in 2010.
