Ok gurls, heres the tea
Sugababes have left their old label since they wasn't putting enough into the upcoming campaign (for obvious reasons, the girls needed a lot of help with this era). They released 'The Complete B's' to end their contract with Island and signed a three-album deal with Sony. This has obviously pushed everything back since they really need to be prepared with their comeback. The single probably won't be out for another month, since they are also recording new tracks with Sony. The album is due in October.
If it means they stand a better chance at coming back successfully, I'm ok with waiting
