A sign of things to come?

Looks like the 'Sugababes' have fallen at the 1st hurdle. Scheduled to perform at a charity gig at Glasgow's Royal Concert Hall, they were forced to 'pull out' due to 'contractual reasons' - apparently Jade Ewen is not officially a 'Sugababe' because she hasn't signed on the dotted line. Now, I'm a very strong believer in karma and so far in the space of a, like, a week there has been reported arguments and now this...I'm just saying! You reap what you sow, no?
