All Saints are set to make a comeback.
A source said: ''The girls are really excited but the decision to make new music almost happened by accident. They had a great time supporting the Backstreet Boys on tour last year performing their old hits and thought there would be no harm done if they messed about together in the studio.
''The stuff they came up with sounded so good they thought, 'Shall we just go for it?' The songs are mainly being written with Shaznay as usual, and have the All Saints vibe running through them, but it's still very modern and pop.''
And the insider insists there is no rivalry between the 'Never Ever' hitmakers and the Spice Girls, who are also rumoured to be making a comeback next year.
The insider added to The Sun on Sunday newspaper: ''It is a complete coincidence that both comebacks could happen at the same time.
