This is why I stated that its not worth flying celebrities around when they are in image changing/enhancing mode, when they're just doing work they're usually pretty civilized.
I think the big question here is who owns the airplane, if its managed and not owned by the certificate holder then there is a good chance they'll get an earful at the very least, and quite possibly have it pulled from their certificate by an angry owner for showing such terrible judgement in who they chose to allow to charter it to. The company may see it as only money, but the airplane owner may view the airplane as an asset that they trusted them with.
