ROSS RETURNS TO PRISON: So, Diana Ross tried to serve her two days in jail. But she couldn't quite get her head round the concept, and kept popping in and out of the jail. She did manage to clock up 22 hours inside at one point, but Judge Cranshaw says that's not enough, and says she's got to go back and do two proper days. Ross' lawyers are appealing, saying "the terms of the sentence" weren't made clear enough. What part of 'two days in prison' is cloudy, exactly?
