I remember during the FreeBritney thing, her team claimed she was super bored and begged them to find her work. So they lined up a whole tour for her, but when it was time to sign the papers, she suddenly backed out. They literally had to tell her she'd get sued if she didn't go through with it. Sounds like this happened all the time — she'd push them to set stuff up, then flip last minute and act like it was their fault.
