Britney said herself she can't trust anyone around her. That's the smart conclusion, you certainly can't. The even smarter conclusion now is to remove yourself from that situation altogether. Leave a forwarding address for the royalties checks and say SEE YA!
I'd say you would have to have a considerably thick skin to spend any appreciable amount of time in Hollowood.

She's constantly dealing with this crap...anyone would go nuts
