All Saints, Atomic Kitten and East 17's collaborative UK tour has been cancelled due to "unforeseen circumstances".
The Another Time, Another Place tour, which would also feature nineties and noughties stars such as Big Brovaz and Ace of Base's Jenny Breggren, was set to take place in November but has now been shelved.
The bands were scheduled to appear at some of the UK's biggest venues, including London's O2 Arena, but Ticketmaster has now cancelled all the listed dates and the official Another Time, Another Place website has been shut down.
None of the acts involved in the tour have commented on the cancellation, but Ticketmaster told a fan on Twitter: "Yes, the tour has been cancelled due to unforeseen circumstances, sorry. All affected customers will be contacted shortly!"
All Saints have recently returned to the limelight after splitting for the second time in 2007. They recently supported the Backstreet Boys on their UK tour, and are reportedly planning to release a new single this summer.
